Hi I really love the sound of LaBella flats, but I play too rarely to "toughen up" my fingers, which means I get blisters pretty fast. Do you guys know of any pure nickel flats or other flats that are easier on the fingers? (I know of Thomastik, but they are too floppy for me) I'm considering going back to Fender pure nickel rounds, but I would prefer to stay with flats. And please, no "Man up!"-remarks.
