i on qv prop right now. there is no pain whatsoever.
simba- if you're having any pain, its probably not the prop. after you dart, message the hell out of it for at least 10 minutes and you'll have no pain. i use an electric messager with heat and it works like a charm. also, you can use a smaller dart for prop. i like to use a 25 guage, 1 inch dart.
