Well Murray I suppose the harder metal would have less wear but what else do you see as an advantage? I see some claims as to making string bending easier, but wouldn't any new or filed fret do the same?
With the way I play it wouldn't make a difference because I stick mostly to chords and a few runs. G,C,&D and anything else is showing off! I am afraid that it will take much more than frets to turn me into a Tony or JP! :-}
