@emilernebro @25jonathan I recently started considering the same issue. As I've been playing more I noticed I naturally gravitated towards pinky anchoring. The problem for me is in the last year as I've gotten deeper into finger style and playing more often and longer, I get a lot of pinky pain and it starts to feel tired. I also might have some nerve issues from an old injury / cupital tunnel issues and sometimes it gets really numb and wants to stay curled up.
I'm considering retraining to not plant my pinky just to avoid the pain/numbness, but since it's so instinctual I'm considering practicing with a rubber hand keeping the pinky tied to ring because its so hard to stop.
