Would I like them to me more environmentally friendly? Hell yes!
The comment was about FSR in general, that people believe it hurts more than woodsball paint. It doesn't. It carries speed for longer that is all. Compare woodsball to tourny ball and you will realize the issue isn't FSR. And yes.. he assuption that .50 cal is 'kid friendly' is because they fire them at MUCH SLOWER speeds for kids. Have you ever been shot by a .43 cal at 250+ ? It still hurts.
I may have a .50 cal FSR on my on my desk right now
