Had a drum instructor one time that watched my hands and told me I wasn't compensating properly on the sticks- that I had a "dead grip". I asked him how he could tell, and he told me that as he watched, the logo on the sticks never moved with respect to the stick centerline while I played. In other words, if I started playing a piece with the logo facing straight up on the top of the stick, it would stay exactly on the top of the stick for the whole piece. And the stick would indeed slowly migrate away from proper balance until I had nothing but the butt left. According to him, if you have a light grip and are compensating the way he thought it should be done, the sticks should slowly and continuously rotate between your fingers as you finesse your grip back to the fulcrum point as soon as you feel any imbalance.
He taught me a warmup exercise where you roll the sticks in sort of a conical motion in a very, very loose grip without striking anything, and work on keeping your fulcrum right where you want it, rolling it in the grip as a part of each "stroke": clockwise in the right hand, counterclockwise in the left. It seemed to work: once you get that as part of a simple warmup and finger stretcher before actually playing a note, it becomes second nature. Anyway, I find that I turn the sticks about one rotation every 3-4 seconds on my ride side, and about a quarter as fast on my snare side (depending greatly on the tempo and the power level of the play, of course). But sure enough, they spin quite nicely while I'm playing now, as I adjust to keep the fulcrum home....
That was a long time ago- 35 years, maybe. I have no idea if that sort of thing is taught anymore- for all I know, it has now been declared to be a horrible thing to do (and it surely doesn't work with traditional asymmetrical fan-shaped brushes, which is why I don't play 'em!). But it sure worked for me at the time, and helped me a lot with dropping sticks, stamina, blistering, and all sorts of other woes I was experiencing back in my misspent youth. Anybody else ever get shown this?
Your mileage may vary: I'm sure as hell not qualified to even play a drum instructor on TV...
