That's been my experience as well. The only injuries I've sustained in no-gi have been more surface injuries like bruises or cuts from catching more stray elbows or knees if lower belts are flailing a little more.My worst injuries are all from Judo. Wrestling and no-gi I've only ever gotten seriously hurt once outside of competition, and that was an injury that could have just as easily have happened in the gi. With the gi I've never really gotten injured, but I find the overuse injuries of gi BJJ (fingers and back mostly) to be worse than anything I get no-gi. Once you develop some strength and flexibility in your neck no-gi's pretty easy on the body.
