Honestly, I think sorting tables by stats like pot size is overrated. I mean yeah, to an extreme you don't want to be on tables with the smallest average pot. But the way the stat is calculated is only over a short term average - table selection really comes down to being in the right seat and having the best mix of opponents where you want them. The pot size average will fluctuate too much to be accurate, but it will be a good gerneral indication of how much action you may get.

I do sort by pot size myself, but I don't automatically go to the top of the list where the biggest pots are. I just sit down at a bunch of tables and then close the ones that are bad.

In choosing your seat you would like to have nits to your left who don't adjust to you stealing. The won't use position like they should so they won't give you trouble. TAG/LAG players are best to have on your right because they will do a better job of exploiting their positional advantage on you by 3betting aggressively, raising your cbets etc. If they're sitting across the table from you this is also good (might even be better than if they're on your right) as you likely won't tangle with them much at all. Fish on your right for isolating is also preferred.
