Tried some Gamma Revelation 16 at 62 lbs that came with my stringing machine. A joy to string with and seems like a decent string (though I never use anything more than 17g these days), but it just gave me too much power. I was drilling them long. Guess I'll go back to poly. Thinking of trying some Kevlar, I need strings that are dead, dead, deader than dead. :-?
