Moving up help

Thanks to a £100 (yes pounds) bonus I'll shortly be receiving PLUS me crushing the site's rly bad players, I'll be min-rolled for 10nl (according to the x by 100 by 20 BRM rule).

Rather than me depositing again on Stars, for the last month, I've been playing exclusively on this euro site in order to build up a better roll. Since this is now achieved, I want to move up...but part of me wants to make sure I'm beating Stars 2nl for at least 10000 hands before I do this. I suspect (or am pretty certain) that the 2nl level on Stars is better than the 4nl on this Euro site.

My options are therefore:

1) move up to £8nl or £10nl on the euro site

2) move up to $5nl or $10nl on Stars

3) move money to a new site and do another month or so of bonus whoring

4) split the money between both sites so I'm rolled for 8nl on euro site and a min buy in for 2nl on Stars, and proceed to beat Stars 2nl for the next month or two.

EDIT: Come to think of it, my roll in USD$ will be much higher since I'm currently playing in GBP.
