Upon installing a new set of D'Addario EXL125's on my strat, I noticed how rough and grinding the plain strings are when bending. The roughness goes away in fairly short order after playing a bit. If I check an unused fret (22nd fret G for example) even after a week of playing - they feel rough I'm assuming becaused they have not been played to smooth out. A couple of concerns come to mind... Does this wear the frets down? Do other sting brands feel this way?
