I over the past few years have tried all sorted of stuff to go down Beverly Westwood on. hitting some speed and massive jumps. iv tried the following.
Heavy duty rubble bags and put yourself in the bag and go down on your back. (always loose control tho)
Normal plastic sled wrapped in visqueen (fast as fcuk just hard to fit in sled)
Pool lilo although this worked ace, first air i got it popped.
& finally the best thing iv ever purchased
SNOW BOB - TRIANGULAR its specialy made for flying down hills in comfort! while still achieving speed and seems to be strong as out.
