People's mouse grip varies immensely. But the one thing that should be easily controlled, in any reasonable case, is the surface. A mouse mat will often reduce friction greatly, and you can augment your mouse with custom teflon "feet". Gamer peripherals, basically. I see a lot of people who just run their mice across their desk, which no doubt works, but is sub-optimal in that it's not a particularly durable surface in most cases. This will lead to scratches, and thus increased friction on top of the noise and now ruined surface. Another thing I've seen is a really nasty build-up of gunk (for lack of a better term) underneath the mouse. All of this adds up to increased friction and a "sticky" feel at times, which results in erratic movement and possibly a need for tighter grip. Then, of course, there's always the option to switch the mice out. A wired option will obviously forgo the batteries, lowering the weight of the unit, at a negligible convenience price.
