Death grip also means using more force than necessary. A properly fitting thumb hole, the span, tapes, everything can play a role. And the ugly part is that it works out for everyone differently. I had 3 experienced players helping me with my release, and each of them made a good contribution - including the bevel, use of tape, and the pitch.
I think that every player has to experiment with all these elements and check what helps, and what not. Tough task, but only ourself can tell whether a change (and even small things can have a huge effect) is helpful or not. and it is not only the "technical" side of the ball, but also the player's release. Things can be very simple, but recognizing them and staying conscious is VERY tough.
But I know, when I make a bad shot (e. g. pulling the ball to the lft because I did not release it properly and hung onto it), I know what to check to get things back to normal - like the weight shift onto the finger tips upon finger and thumb insertion. Small, basic things, but you need to become aware of them. You cannot change or improve what you actually do not know.
