6-Handed vs. 9-Handed Sit n Go's?

Which do you find more profitable, and which should I focus on?

Depends on how aggressive u are prepared to play.

6 handed sit n gos will see the blinds move more quickly so you have to widen your playing hand range and bet more frequently.

9 handed allows you to be more patient and you can wait for better hands more than u would in 6 handed.

So I would say profitability ie relative to your style:

Patient style - 9 handed is better for you
Aggressive style - 6 handed is better.

I like 6 handed, I like to play more agro. 9 handed..I dont like to sit that long for a one table sng. So my pick is 6 handed.

I prefer the six handed sitngo its faster and you can play more of them in a shorter period of time. your also less likely to see 3 or 4 big hands at one time so the risk of being burned is less
