I change throughout a set depending on how I'm playing. I usually plant my pinky for fingerstyle picking. Strumming is freefloating with palm muting as needed...whatever works really.
so how are you at time and rhythm?
do you value a good feel for rhythm in guitar playing?
I consider guitar to be primarily a rhythm instrument and I'm at home locking in with drums and bass. I'm allergic to the idea that melody, harmony etc are all about guitar...
