I am wondering if there is a sub-type of string out there that is geared towards their ability to be fingered quickly. I am not a beginning player and I don't have stamina or callouse issues (DB player), but sometimes I want to beable to play Tower of Power-like sixteenths a little more easily and the like. Does anyone know of any strings that could help me? I like both stainless rounds and nickel rounds, haven't tried flats yet. Thanks.
