lol. You should move the limits in relation of your bankroll. But I'm pretty sure that if you can win in 5$ you should beat the 2$ or 1$ stg.
When I started to play stg I was playing double or nothing at pokerstars
, were you learn to be quite and think before you move to the 9player 50% 30% 20%
Well if you are getting out from the blinds, go and try the slowest game. You must incrase your roi so you can get more exp in this kind of stng.
At stars I was playing 1.10 45 players, when I was playing 3.30 I did it better cuz it was the same scheme and strategy cuz the people doesn't change only the buy in was higgerbut really better than 1.10 cuz here the people was about "OH im playing with higher buy in so this people should play good" that's why they tight more and try to play good but they always make mistakes.
So IMO play 1$ and 2$ and when you incrase your roll then go to 5$
