Thanks for the input everyone.

I've played some lowstakes HU sng's on stars - only sat on tables with players already sitting, so I basically played all the regs, some with insane ROI's, but objectively abysmally bad players. I'm supremely confident I could beat most of them without looking at my holecards, honest to god.
I'm still going to go with pkr cos I never played it, so I'm curious. Plus I get 40% RB till october and 30% after that, plus deposit bonus etc.

I'll start a new operation once I can think of a good SN for pkr. :P
