In other words.........
Try to play the 4-deck game, if you can find one (not many outside the London centre). Have a large bankroll, and spread it wildly. Be exceptionally accurate with the count, speed isn't necessarily an issue, but nice to have. Also use as many indices as you feel comfortable with, but keep it as simple as possible, as mistakes can be costly. Have fun, the UK game is very difficult, so be very detached from the money, because you are going to experience many a bad beat.
The game can be beaten, but you have to be very disciplined.
What part of the country are you playing?
