I have been beating the $15 spins with a 38% itm adjusted over the last 1500 games. Probably some ev run good. Anyway, my bankroll is up to $4200 and I want to take a 50 bi shot at the 30's. I play on stars btw. How big is the skill difference between the average players? Obv there are more regs but is it significantly harder? Advice on the differences and drop in win rate  from someone who plays these games regularly would be much appreciated. Thanks.
