Why don't you move up to higher levels now?
...Well, I can't at the moment because I cashed out most of my BR. So, I'm only rolled for 2nl and small SNGs.
For me, this is all recreational. I play when I can just to have fun and sometimes I eventually make some money if I'm consistent or I do well in a big MTT. When I can fully focus on it, I'll play higher stakes, but right now with school and work, I barely put in a couple hours a day. So, I just play small stakes just to play.
If you're multi-tabling I assume you are a winning player overall. I mean, people generally play for a mixture of fun and profit, and more tables does not = more fun, and if you're not a winning player at more tables that = less profit. So I'm concluding that you make some sort of profit. And there's more profit to be made at higher levels.
...I sometimes play as high as 24 tables at 2nl, but that's all for fun. I make some profit, but not as much. If I'm playing for profit, then I'll drop down to 9-12 tables. I really don't expect to make much quickly with 2nl. Maybe $50 in a month if I'm consistent, but that's it. So, I'm not playing it to make those huge jumps in the BR. Again, its all recreation-the profits are just an added bonus.
I agree that there is more profits at the higher levels, but a) I'm not rolled for higher limits and b) I just don't feel like playing them right now. I don't think I'm missing out on anything by not moving up.
