Do the weight of skis matter?

I got px18s on my 79 recoils, i could have gotten pivots but i would have had to pay and extra 150 so i whent with the px18s wich are a bit heavy
 
Depends on the weight difference.

One park ski vs another; it's probably pretty minimal

A park ski vs a pow ski where there is 500 grams + difference in weight; you will notice it.

Tbh the most important weight is that at the tips of your skis as that is the part of the ski which takes the most effort to spin. Anything underfoot shouldn't matter too much.
 
i hadn't ever noticed weight until I got moment's last year and they were ridiculously light. i think it made rails a little easier.
 
More weight in the center of the ski. Less on the sides. Try spinning in a desk chair with your feet extended and then tuck them in. You'll see what I mean.
 
Meh, after a couple of runs you probably won't really notice the difference between ski A and ski B, besides, heavier skis are generally more durable.
 
it's not super important but you will notice it. bindings make minimal difference because they are so close to your center of rotation, but heavier and longer skis make a difference due to centrifugal force.
 
I certainly think so, especially if you are doing shuffles, shifties, switchups, touring... Light skis rule if you ask me.
 
wrong type of force homie, one with the " f " is the fake force that pushes out. Spinning would have somthing to do with rotational intertia. It takes more force to move a object with a heavery mass.
 
i'd like to think they do, I'm on longer and pop-ier skis than last year(not noticeably lighter),

switched the bindings to marker squires about a week ago after 25 days and noticed a huge difference, wasn't really expecting it but it helped me out

con to squires though the highest din is 11 which might not be enough later on,

 
weight matters but swing weight matters more. Light skis feel better but to light might not have good flex and stiffness anymore.
 
it was easier to do swaps and stuff with lighter skis, definitely. plus thats just my opinion, im not saying its for everyone.
 
weight being at the center of the ski as opposed to the tips will help with spinning regardless of whether your skis are symmetrical.
 
What do you mean about helping?

Weight being at center of ski just makes radius to COM equal in relation to both tips, ie moment of inertia. Moving a binding backwards or forwards makes no difference since the rotational energy is in an isolated system, no external dissipative forces. (I'm going to neglect rotational air resistance).
 
Rotational weight (i.e. swing weight) actually makes a pretty huge difference when it comes down to the weight of your skis. A few ounces of weight difference between two park skis can drastically affect the feel of rotational weight, making the skis seem heavier or lighter when you're spinning. You could also argue that more weight makes you spin faster (more weight, more inertia, more centrifugal force, more spinning).

Although they don't compare that well, think about bike wheels. The best way to make a bike feel lighter is to use lightweight parts on your wheels - rotational weight makes the most difference. Bike wheels are rotating way faster than skis ever will though...but the same basic principals apply.

YOU HAS SCIENCE
 
My opinion is that light skis feel nicer doing switchups on rails and such, but feel way too floppy on jumps, and visa versa for heavy skis
 
This guy knows what's up.

The only reason I can see weight playing a role is for rotation because all objects under the influence of gravity fall at 9.8 ms^-2 regardless of their weight.

Rotation is governed by torque which is represented by the cross product of the moment arm and force. Moment arm is not really something that needs to be considered (binding placement) but force is a direct result of mass and acceleration.

See where mass or weight comes into play?
 
i have armada ar6's with px 12 jibs on them and they're pretty heavy... the Px12's are almost too heavy i think...

then again i'm 5'9 and ride 181's...
 
well thats a bias way to put it, of course you gunna want weight for a lot of reasons, jumps... maybe notbut any jibs your gunna want weight, same with halfpipe, as well as powder
 
This. You get used to anything. It'll only throw you if you switch to skis that are way different than what you've been riding recently.
 
Another basic fact is that it takes more energy (force) to launch a heavier object, yes you'll fall at the same speed with cinder blocks taped to your feet rather than feathers, but you'll jump a lot higher with the feathers.

Again, if the weight difference is small (ounces) it will be most likely imperceptible even on bigger jumps. However if you're going from some real old skis to new ones (all in all my Boot-binding-ski setup this year will be ~5 lbs lighter than last years) you will probably notice a difference if mid-jump you try to raise your knees to your chest. This is because your center of gravity can change considerably based upon a significant change in distal weight (eg. your feet)

force has nothing do to with skiing unless your about to hit something, but im guessing the overall weight of ski will effect your pop and when you set, other than that when your in the air, it should be the same, not effects
 
by weight being in the center helping, I mean that if you compare a 1500g ski with most of its weight at the tips, with a 1500g ski with its weight in the center and lighter tips, it will be easier to spin on the one with the weight in the center.
 
I got a set of DPS lotus 120s this year.

Positives of the weight savings. Carrying them in your arms. They are easy to pick up with your hands.

Negatives. They get deflected when crossing tracks. They don't have the mass to really power through anything. This is also a function of the soft flex in the tips.

Touring. The ski mostly slides on the snow, so you aren't really lifting it up every step. binding and boot weight makes a huge difference. ski weight, not so much. Also, skis tend to build up snow on the top sheets. A big fat ski tends to carry more snow, which reduces the weight savings.

Not that the skis are bad. They are a great ski. Just that the weight savings isn't really that important for skiing down. Except they are a joy to carry in your arms or on your back.

I don't ski park, I am sure that the reduced swing weight would be an asset there. Although it's not going to make you all of a sudden go from having trouble getting a 7 around, to stomping 10s. It's really the operator.
 
heavyer skis you have more control of in the air. They are a tiny bit harder to huck 3 ups on rails but other than that heavyer FTW
 
yeah, it does matter. but the extent to which it matters to any given person can vary hugely. i'd much rather have a slightly heaver, more durable ski than a slightly lighter, less durable ski. obviously a lighter ski isn't inherently less durable, yet from my experience they often are.
 
Don't be a weight weenie. Go to the gym. Comparing which park skis are heavy vs light is like comparing how much healthier a Big Mac is to a Whopper.
 
As far as ski weight, it can be noticeable / make a slight difference. I always lol when people say that binding weight matters. It doesn't at all, they weight is basically all underfoot. The only difference it makes is when you are carrying your skis.
