After owning and using CAST as well as having skied shifts, kingpins, g3 zeds, frames, and daymakers, heres my take:
Pros:
- You get to ski a pivot in the backcountry
- its the ONLY touring binding il ski regularly in bounds (sorry AMER, 2 prereleases, a broken binding, and a lost ski later il never ski your shift again)
- bombproof durability. Nothings gone wrong and i cant see anything breaking.
- CAST is a great company with amazing warranty should I need it.
- You can tour on any skis you want- its like $80 for the second ski kit if you have more pivots and you can use it with any din heelpiece. (cast themselves gave me the OK to mount p14 heels on a second set as long as I used my metal toe)
- The weight distribution feels VERY natural while skinning since your heel isnt locked in like a frame binding or daymaker. ~950 grams on the uphill feels way lighter due to the heelpiece- the weight on the heel makes kick turns easier and also helps my crappy skinning technique by keeping my ski on the snow.
- The ultimate slackcountry weapon. (couple BC laps in the morning, then ride lifts at lunch)
Cons:
- It is heavier than most other options for being in the backcountry
- transitions- i bring a bouldering brush with me to clear all the snow. Fiddly transitions (i can still do with mitts on) that you definitely improve over time, but no matter how fast you get you still cant transition with skis on.
- pack space for the alpine toe pieces- you wouldnt think its much, but when you go on a dedicated pin setup you notice the free space.
- $$$ if you dont have pivots. Fairly inexpensive compared to a freeraider if you do have pivots.
- Cant use a dedicated touring boot, have to use a boot compatible with a pivot.
When I use it-
My view is that CAST turns an alpine setup into a setup that can tour- not a dedicated touring setup. 8/10 times i venture into the backcountry, i reach for my zeds- saving 700g + pack space usually means i can get an extra lap in, and am not wiped for huge days.
That being said, I always reach for a set of sticks with CAST on them whenever I know im going to be doing a decently big/gnarly line (especially where I know i need my skis off at the top to finish a bootpack). I will also grab them when i will be leaving a resort so I can come back to ride up a chair a few times after a morning slackcountry lap without having to go back to the car to switch skis. Ive also used them once for a Backcountry booter day.
Who is CAST for?
I would get cast if you answer YES to any of these questions:
- do you really ski hard enough in the backcountry to need CAST? I know my ballsiness plummets when i know ski patrols not there to bail me out.
- If not, do you only go a couple times a year and want to just use your in bounds skis?
- does your local have slackcountry?
- Do you already have p15/18s and boots with tech inserts (Cant use touring soles with pivots, have to be Alpine or GW with tech inserts) and are looking to get in the BC for cheap?
- Do you want to be able to tour on multiple skis?
- Do you care way more about the ride down, and not as much about being 100% efficient on the way up and on transitions?
- Do you want to have a durable setup and support a great company?
If you didnt answer yes to at least one or two of these, I would suggest being real with yourself- pin binding technology has come a long ways. a binding like a freeraider or a zed on a somewhat lighter ski still has great downhill performance and also is night and day on the uphill.
Final Thoughts
CAST is great at what it does (downhill confidence, 50/50 skis, 1-5 tours/year), but IMO isnt worth to have on a dedicated touring ski. Its for an in bounds ski that has the ability to tour. I love my CAST system and will always have it on at least one or 2 skis, but will usually reach for a lighter ~350g binding over CAST ~950g. Its a great compliment to my lighter setup, but i know if i only had cast and toured more than 5 times a year i know i would want something lighter. I also know that if i only had a light setup, i would want cast for days where i do gnarly lines or go in the sidecountry.
