Well for me, if I'm chasing a new trick, I'll just start jammin' a prime or a pop (or like, anything with crazy grip) as my main. I'll just slay until I get the new trick down consistently, then I'll switch to a dama with a bit less grip (or just slay until the original dama starts losing grip, honestly haha). Eventually the trick becomes so easy and consistent that it doesn't even feel weird to pick up an Ozora or a natty and bust it out. As for the beeswaxed tamas, in my experience it sort of does give me extra grip (not from the wax itself really, just makes it feel like it's already broken in). The way I was taught to apply the wax was to rub it on, heat it until the wax melts, rub it in (repeat for desired number of coats) and then heat and wipe away excess (that way, it's all IN the wood, not on the outside making it sticky).
