It can be done sucessfully...just maybe not on purpose.
Tony Haikonen pulled off a successful/accidental barrel-roll in the 1995 snowcross final at Canterbury. I think it is on one of the Havok, Wreck and Roll Video from '96 or '97. Time to check the VHS archives!
I would have to think a higher center of gravity sled would be easier to pull this off, just a thought. Thanks for the input, can't wait to see it done!
Dedication. Looked at your vids on youtube, I can't believe some of those ya never let go of, ouch! Keep trying, I want to see it in video, now that would sell.
