i would pull my money together and go 1 site at a time, first of all - 2nd I would play cash games - i just think there is a more solid rate of return instead of sporadic with the tempting huge payouts...Also, do some bonus chasing? do you like playing limit?

What I did over the last month is lost most of my BR, took my last $100 and started grinding 10NL - I was pissed that I lost, but at the same time it got me to realize that i had a lot to learn and to swallow some pride - Now i'm back up to $700 and back to 25NL - granted, its very low limit but the fact that i grinded it up myself im kinda proud of -

otherwise, is the money easily replaceable? Maybe do the $4.40's at Stars - those are really good for a little 180 man tourney - clock a couple of decent finishes or a win and your BR will be in good shape - i'll have to let everyone else answer the SNG tactics though - i just try to play cash with occasional MTT's
