Don’t know, but have you ever noticed that a lot of “Bear Paw’d” fellas end up playing the mandolin?
Watch your elbow position also… A way to get elbow position and train fingers is to practice fretting with only the tips of your fingers. I make a point in trying to never use a finger as a “bar” (lay a finger down across a string vs using the tip) when playing lead. Sure sometimes you have to, but I am conscious of it and try to shy away from it if it is not needed. Try playing with the tips and watch where your elbow position ends up…elbow position can compensate for short fingers.
As mentioned before, I played some collegiate golf in my day and at the end of the day the consistent ones that were always at the top of the leader board were the ones that understood and disciplined themselves on FUNDAMENTALS, I was not as good as those guys because my fundamentals were not as honed, so when I took up guitar I told myself that fundamentals from a technical standpoint was gonna be my main focus.
Not our style, but take the time to peak at Steve Vai’s fingers…dude could play a 4" wide nut width with no problem where the short stubby finger guys like me don’t stand a chance!
I will say that my fingers on my fretting hand are at least 1/8" longer than the fingers on my other hand, and much more slender…I am pretty sure this comes from the aerobic workout they get from playing the guitar for 20 some years.
As others mentioned “flexibility” is pretty important. On guitar practice your 3 notes per string G major scale in the 3rd position to work on flexibility.
