Any nuggets of wisdom or specific exercises for playing heel up with the beater off the head? I don't find that I need it often, but it would be a nice tool to have in the tool kit.
not to "horn in" on @Push pull stroke's answer - which I am sure will be informative
but for me, to get the beater off the head with heel up, I just had to relearn some upper body balance - by way of good core strength - or, like my drum teachers and parents always said: "don't slouch". It took me about 6 months to get used to it.
Honestly, I think I use "beater off the head" in about 10% of my playing though, so it is not a tool that comes out of the box much, but it iis there
