Need New Game

Okay, so I've been playing the $13 6max 18-man MTTs on PokerStars successfully for about 6 months for now, and since I've been on break from school for a week I've made over $300 playing a little every day. Just trying to make the point that I have a large enough data sampling to be confident in my game. The problem is that the next level ($38) never fills up. I have never seen more than 3 people waiting in one of those. I want to make more money, but I can't go up in levels anymore, obviously.

Where would you suggest I try going from this point? I just want another easy game that I can get higher in stakes with.

Oh. I wanted to add that I've tried moving to 9/10max, but I have trouble being successful at that. If you have tips in that regard, they'd be welcome as well.

Isn't there a 27 man or a 45 man sng there at PS? You could try that (but I know with the 18 seaters the timeline of playtime are easier to manage).

woah if you're making 300 a week... why bother moving up lol? Whats the pay structure like for the $13 MTT anyways?

They only have STT, 12-man, and 18-man at PS.

The payout structure is 80ish, 60ish, 40ish, 20ish.

And actually, the $38 does seem to fill up every 15-30 min, but I'm still curious about branching out.
