Thanks for responding. I don't like the dunlop nylon picks they sound "scratchy." As far as muscle development goes, I have been playing nearly 30 years. Fiddle rosin is too sticky, sticks to everything & I will get it everywhere-trust me neatness is not one of my strong points. I think I will try some of the gorilla snot & see how that goes. In the mean while I have a few medium fender picks I drilled some holes in that I am gonna try out & see how they hold up. Thanks again, Charcloth
