Dude, tried to add you on msn, but no luck.
Tj...I almost called you on my way up to washington last week, but lost your contact info when i dropped my phone on the floor.oh well . Next time?
Turbines are funny because once you get one you can usually get them in quite a few different tricks. You have to think about it like a large spiral that you're moving towards the center in. once you hit that center point momentum should be what carries you forwards to backwards and forwards again. http://www.youtube.com/watch?v=mpzPY_a9GRY&feature=channel_pageWhen I go from forwards steamroller and scuff backwards, you can kind of see the spiral I'm talking about. The center is the pivot point where your tire literally has nowhere to go BUT forwards. I still think your biggest problem is your posture during the trick. Loosen up a bit, do some stretching, and stop thinking about the concept of a "steamroller". Just tell yourself that you want to make this motion on a bike, and don't worry about the trick itself. It sounds kind of like metaphysical, but that's helped me get over hurdles when I ride.
