You can't put the hands up on MF? I don't think I could stand NOT putting up the hands, I even did on my first MF ride because I knew I wouldn't be scared for long and would want them up, but to keep my hands down would just eat at my soul!
Same for Hypersonic, which you shouldn't have a problem not taking pictures from because taking a picture from XLC is the last thing you're gonna wanna do, they said they wouldn't launch if they saw the hands up, but as soon as that thing clicks and grabs, I don't think they're stopping you, hands up or not, which I don't know if it could hurt or not(didn't feel like anything, it's harder trying to put 'em up AFTER launching so you have 'em up going up the hill:))?
You shouldn't try to take pictures from everything you ride, you're risking it there. The more you do it, the more oppurtunities you will have to drop your stuff. So doing it in "moderation", and not talking about it are cool, IMO, but I don't like to say I'm cool with it, because as soon as more people do it, I'll be hit with the one camera that the one fool who's dropping thiers drops. Don't ask, don't tell, or something.......
