The Ringfinger for Manos O

i used to, but how my middle finger's all jacked up, and now i've siuse relegs to thepoin ye. I think i developed a lot of strength for my middle finger ecause it would take the most of the weight on climbs. If i were to grab a hole, i woud grab pinky and thumb first, and then i would roll the rest of my fingers on. And if i didn't need my index finger, i wouldn't use it. It's always like fastening to me how, like, it's like, what makes some one choose their pointer finger verses their middle finger?
