Replying to Helmets and other suggestings

How many people on here wear a helmet? I don't because I lost mine 2 years ago and havent gotten a new one yet. Also, I just moved out west from WI and I STILL have not hit the terrain park here at Keystone/Breck/Vail, etc. because i am afraid of the bigger jumps. Not afraind to hit them, but afraind to throw tricks off them. In WI I could throw and land 9s, cork 7s, dspin 7s, misty 7s, and a wierd switch 7 rodeo variant off the smaller midwest kickers. Out here, I can barely land a 360 off these things. Any pointers and keeping control in the air and getting used to these larger jumps?
