i went with no experiance and did the wall on the last day of sking. it was great fun so i did it again. don't listen to these stupid prats who rattle on this forum very day like they own it. just listen to your instructor if he/she says your good enough then try it.
if you do tyring it just go for it, backing out is usually why people fall on it.
No PATMAN! 5 didn't do it!
I did it, I didn't fall, I didn't die, I didn't break any bones and had a great time. I have gone on to do various black runs and the wall is now a walk in a park, a small one at that! Have some fun guy, if u ain't up for it, don't do an extreme sport!
