What poker site should I try?

[Bluegrassplayer]

At the moment I am only playing cards about 2-3 times a week. It's a 1/2 200 max buy in to open then you can buy in for the average chip stack after. I'm averaging approx $1500 a month there over the past year and a half, playing anywhere from 2-12 hours a session. The rake is very minimal, 1-3 dollars, making up a lot of the my profit.

I also almost always lose any time I play less than 6 handed, and the closer I go from 10 to 6 the more my profit goes downhill as well.

So based off of this: can I be a winning online player? What is the best online site for me to play at based off of rake and wanking to play full tables as much as possible? Thanks ahead of time.
