If you love live pokes it seems you probably enjoy the social aspect of the game more than the actual poker but also likes the poker a bit. If saying over £1 is tough on sky, then your probably not good enough to be playing NL200 anywhere online. FWIW, live cash is terrible (in casino's in general) and non comparible to online cash. Live MTT's are also a lot weaker than online MTT's.
Why is it you want to play poker so much when off work ? If your 3 tabling it sounds like you've not played to much poker so stop worrying about the BI's and play a small BI MTT schedule and see how you enjoy that IMO.

Its because i am stuck with my leg up in the air for 2 weeks, i can either watch tv, xbox or play poker anything else will be beyond me! I think you're right regarding a small BI mtt schedule, what i might do is hook up another screen so i can play 8 + tables but play small BI's. I agree live cash is terrible in a lot of places, my nearest casino is nearly a two hour drive but is worth the trip because most the regs are terrible players.
