My suggestion... become a really sound player in STT SNG (9-plyr). After you've researched/studied the game (found leaks, learn optimal play/strategy, check out HH posts, review games via auto replayer, read Collin Moshmann's Book SNG Strategy, etc. etc.)... then move onto playing some of the 27's. My experience has been that the play in the 27's is particularly soft..... perhaps alot of players who weren't able to profit in the STT's. Majority of players are pretty bad but there's a small minority who play these and do really well in them, with very large profit (hi ROI from multi-tabling the 27's). It's like they're on to something, lol.
I don't particularly care of the 'turbo' 45's on Stars. Again there's a small number of players who seem to profit well from them, but is just a mass bingo fest imo - blinds escalate rapidly & game becomes push/fold fairly early... players also seem to call down really light in them so you end up having to have cards when you're in shove mode.
The 45 reg. speed are SNGs that are often played by MTT players as their 'bread & butter' game (something to keep the bankroll going between decent MTT cashes). The games I've had most experience with in the 45's is Fulltilt $10 buyins. Around 1/3 of the players are real bad, another 1/3 half decent and another 1/3 who are very good (you'll see some players in these who are up net profit of over $20K). It helps to know who are the regs. in these games but doesn't take long to know them as they'll be in most of the ones you reg. for if you get into them.
It's possible to sustain a higher ROI by playing the multi-table SNGs but at the same time, one must be prepared for going on dryspells between cashes (losing 10 in-a-row is pretty normal and 20 in-a-row is not uncommon either). There's actually a poker forum where the members of it play mainly the 45's (alot of them at the $10 - $24 buyin level). A bunch of them are also MTT players. The info. I posted here saying "expect to lose 10 or 20 in-a-row" is stuff I've viewed while on that site, written by players who are regularly winning players with alot of experience.
Multi-table SNG's have the neat thing of having your table become short-handed on a few occassios during the game. Being familiar with (and good at) short-handed play is pretty essential for playing these.
I could try to dig up some articles/strategy on playing 45's if anyone is interested.
