$10+1: Shorthand SNG's at Pacific

[eniven]

Hi,
I've been playing shorthanded SNG's at Pacific lately... The structure is as follows:

-$10+1
-5 man
-Top 3 payout (50%, 30%, 20% - so, 3rd place loses $1)
-800 chips to start
-blinds up every 15 hands

Personally, I'm averaging an ROI of 10%. However, I'm winning 30% of the time (i.e. more than my fair share if everything were equal) and cashing 67% of the time (still slightly more than my fair share). Of course, in this case you can cash and still lose...

My questions are as follows:
-Which do you guys prefer to play, shorthand SNG's or longhand SNG's and why?
-Should one expect the same ROI in a shorthand SNG versus a full table SNG?

One other thing I would add is that I find it difficult to play the tight is right strategy early on, as is generally recommended in the first few levels. The blinds come around much quicker obviously and I feel compelled to loosen up a little bit. Any comments on starting hands in the early stages of shorthanded SNG's?

Thanks very much for any help,
Eric
