Robin Trower told me he likes a pick when the tip gets all serrated and worn, he throws picks all over the floor on the stage.I"m very sensitive on the tip shape.
It really affects attack.
I like them worn a bit, not too pointy but not too rounded.
I re-shape them with sandpaper as needed, and bevel the edges a bit.
I've been using the Dunlop Gator Grip 1.5mm the last few years.
I put score lines across them with a utility knife to add grippy-ness to them.
It's been so long using the same 6 or so I don't recall how the stock tip feels.
He says if he drops or loses his pick on stage: he just bends down and grabs another one off the floor cause they are scattered everywhere.
