Your ski is shaped like a curve. Get one of your skis and lay it flat on the ground. You will notice the center is higher than the tip and tail. That height is camber.
hand your skis upside down, supported only by the tips and tails....place a 5-pound weight on each ski...let it sit for a few weeks....
Many people store their skis locked together and if your garage is too humid the core will de-camber during the summer...best to keep em seperate and upside down...even just the weight of the binding will help....
yes I understand camber (I have predators). Im just saying, you can't get more camber into a ski (if you dont use it, you loose it) so puttign the books on and stuff might help KEEP what you have, to not loose more.
1) Make sure when you store your skis during the summer you do not have them strapped together tightly...best to seperate them. It is also good to loosen the DIN on your bindings down to their lowest setting (keeps the springs in better shape)
2) You can definetly try hanging them upside down as a previosuly described....it would work on any ski....but how much camber do you really need on powder skis. Plus the maided are ultra-soft, you probably would not notice much of a difference.
These tips are really for those of you who have skis that have over 75+ days on them or are 2-years old....newer sticks should not have this problem, if they do it should be covered by the company and they will likely replace them
I always store them properly, with a few pairs of race skis you dont want to go ruining them. The PE's just lost camber from skiing them not from improper storage
