And I've seen some great professional players use some very unethical right hand technique: Van Halen, Pat Metheny, etc..
If you find you can't play as fast as you'd like too no matter how much you practice, or your always a little sloppy, or you get frustrated cause your a very hot or cold player,or you don't have the endurance to play long phrases, then you should examine your own technique and try something different. It is not easy to change technique! It will take a couple of gruelling months of practicing in front of the mirror before you get comfortable w/it.
