I would try the 180man´s, but not on fulltilt (traffic). Transfer the bankroll to PokerStars and play the turbo 180man´s (for instance $2.20), these are a good bankroll builder in my opinion and experience...
TRAFFIC??
That only comes in to play when playing an uncapped entry tourney, not a 180 seat SnG. The amount of traffic doesn't determine how well you'll do there. There are 180 seats. Thats it. If anything, the more traffic, the faster the games fill, so its actually beneficial.
I assume you are really referring to the level of play at FT? (which is by the way the same as Stars, as the big two sites).
I have a question, should I have chips for tea tonight, or pasta?
hmmm, should I wear a red shirt or a blue one?
The answer to these and your question comes down to preference.
Which do you prefer playing in and do better at, MTT's or SnG's?
No-one else can decide that for you, as much as they will try.
I feel this is all relative because, as PokerOrifice points out, you are on a mission to recover losses, which NEVER ends well.
For me, MTT's offer better value but take a while to complete.
If your that impatient to recover your losses, attempt the SnG's.
