Hey. I'm pretty new to sngs, but so far I've been fairing pretty well at the partypoker 10+1s. My bankroll is around 350, and I'm wondering how long I'm gonna want to wait until I try moving up to the 20+2s. So first of all, what sort of bankroll am I going to want to have to move up to 20+2s, and secondly, is there any noticable difference in the style/level of play between the 10+1 and the 20+2 sit-n-gos?
