The best table selection is still to open tables. You'll have to learn some heads-up against semi-decent players otherwise it can backfire, but it's the way to go imo.
The 250bb tables on stars are still the softest imo. Buy in for 100 if you don't want to play deep. - The regs will be opening wide because of the antes and the deep stacks, and you can exploit that massively by 3-betting a wide range IP because their opening ranges are too wide and their opening sizes too big against a 100bb stack in lP.
