OK, here's one to get the ball rolling. Does the length of your fretting fingers impact your playing ability? It always seems to me that the top players all have relatively long fingers and are therefore able to span more of the fret board at any one time and also make playing barre chords look a doddle. I have relatively short fingers and have always found barre chords a real pain so my natural inclination is to use the thumb to wrap over the E and A strings. Anyone have any opinions on this?
