Thanks for all the replies. And thanks for the tip excession, turns out Pacific still have that offer so now I have 100$ more.
However, the site sucks and it's only possible to play 1 (one!) table at the time. So a shortstack try is out of the question there. As is playing low limits, I'm not gonna sit playing one table. The only thing I can think of is playing 6max, that requires some attention. But they don't even have that. Only full ring at those limits. And I don't like limit. I'm actually tempted to take my 100$ of bonus money and gamble at the higher limit tables. I could shortstack the 400NL tables
As to playing Omaha, I appreciate the suggestion piers, but I think I'm gonna listen to black knight and keep away. I don't think now is the time to learn a new game.
So that leaves 100$ of bonusmoney at pacific I don't know where to invest..
And 474$ in my Neteller account, which I'll either continue bonuswhoring with or deposit at some site and do a shortstack run... I think.
