I just started jumping the camera this year. Picked up a new hobby in photography last winter so decided to mount it on a helmet this summer. Decided to pick up some new gear this winter and don't want to buy something if I can't eventually incorporate it into skydiving. I love this sport everyone worries about you. No worries only jumping it with 2 or 3 ways so far.

So I'm looking for a flash for my rebel XTI. What is everyone using? I was thinking that a ring flash would be best because one mounted on the top would make the ride to altitude in the cessna that much more difficult. Any ideas?
