Wow, 15 feet sounds high for just crash pad protection. It may be OK for those who have not suffered a concussion but most concussions include a neck injury and 15 feet can result in quite a neck injury. I know some claim crash pads are good for up to 15 feet but please be careful.

I have too many family members who have been injured or had close calls. Castlerock, Lover's Leap, Yosemite, and in between.
