Limit player seeking advice

[pshabi]

Hello STT forum,

I am a 5/10 6-max, limidonk at Party Poker. The increased monster rake, my decreasing winrate, and some boredom have led me to leave my familiar realm in search of something different.

When at work, or when I need a change of pace, I'll play a Turbo27 at Stars. I've done pretty well at these, and it got me wondering. I am thinking of playing a run of Turbo/Speed SNGs to see what kind of profit I can turn. I've got a few questions that I hope someone will be kind enough to help me with.

1) Party or Stars? I have "unmentionable" at Party. I also have a decent roll at Stars. Party 22s, 33s? Stars 27s or 55s? Roll requirements?

2) How much tougher are the Stars 55s than the 27s?

3) Which tourneys, stars or Party, complete quicker?

4) What type of sample size is usually considered decent for looking at results?

5) How many multitabling, 2+2ers play in these games? More at one site or the other?

6) How many tourneys should I start out multitabling? 2,3? Probably just a personal preference here, but I'm covering all bases.

Is there anything else I should be considerings here? Anything important I overlooked? Any help or information is greatly appreciated.
