If you're standing them on the bases anyway, using BBs probably doesn't take any longer, but personally I don't bother with that. I just dump them on a tray, which has a piece of wire screen laying on the bottom. They can pile up 2-3 deep with no issues.
Also, a note about shaking by hand instead of using a tumbler - it only takes 10-20 seconds of shaking, but you should be shaking hard enough to feel like it's a little bit of a workout, or at least a warmup exercise. Not just gently rolling them around in the tub. You want to generate some static, and get that powder flying around in the tub to coat everything.
