How high do I need to get on my regular jumps for a backroll? So far the best I can manage is about 3 feet of height, occasionally close to 4 feet. With the old 1984 Baretta that I use, the wake probably isn't big enough to easily get more than that.
Here's a video with my first backroll attempts ever, plus a few other jumps where I was going for distance, not height.
