Jef147: If we also take into account that N8 rake is MUCH higher than Stars then you should avoid being a GTO whizz in order to beat the games.
FYP. Perhaps the biggest mistake of these HS pros is that they're out of touch with the population tendencies of the micros and don't exploit bad regs (and maybe even fish) hard enough. GTO play is likely simply -EV with this rake.
Besides, the reason why Spraggy is struggling at Stars is that they're reg-infested AF.
Also, as Doug once mentioned, cash games aren't the best bankroll building tool (but mind that PLO has 3% rake at N8 as opposed to the industry standard of 5%, and the caps don't really matter at the micros). If you'd like to play with 2 hole cards, start with Fortune Spin and MTTs and switch to another poker format only when the BR reaches $2K or so.
