Is this maybe a side effect of crimping a lot? As in,if you're always climbing with thumb on then that's effectively supporting the index finger and it therefore is weaker/under-developed?Pure speculation. Can see it going the other way actually, I.e. having your thumb on puts more force through index making it stronger? I don't know.
I have always been strongest on my index and middle fingers. The ring finger just feels relatively unstable. I'm convinced it's utterly useless and all the work is being done by front two. I've never understood these people who will put middle two into pockets and hold them open handed. Looks like a recipe for a pop to me.People have quizzed me on why I use front two in funny little pockets like that and it's always just felt natural. Like, how could the ring finger be anywhere like as strong?
One thing that came out a couple of times and (bias claxon) resonated with me - was that I've really only had pulley damage on my ring finger - which others also commented on.
It just doesn't make sense to me.
