I don't have a practice tree.....yet. I'll see what happens this weekend, it being Fathers day and all. Maybe, just maybe. I think the helmet cam will be much smoother, I'll just have to give it a try and see what happens. My son's first time trial netted him a 512 light, so I have my work cut out for me in that respect. I always have raw horsepower to fall back on. hehehe
