HU SNGs

[Aquinas]

Anyone play these things a lot? I've been trying my hand at the 100+5 and 200+10 on pacific, and have been running into a lot of fools (hyperaggressive folks who give u their stack if u slow play top pair and tight people who like to fold preflop from the small blind). Anyone play these regularly? I'm trying to get an idea what roi I will be able to maintain when my hot streak ends (hot not cardwise but playerwise :P ). Right now it's a silly 22%.
I decided to try them since I feel I need training for the higher buyin events when we reach HU with low blinds. After a few weeks of them I plan to go to the shorthand 200+10 events (which pays top 2 ).

3 wins out of 5 to turn a profit. About 10 mins per match average on the $10's there. Assuming it's the same for the 100's you'd make about $75/hr. Not a bad rate, but how does that compare the the 5 or 6 handed SnG's at that level?

Not sure yet. I've only played 10 shorthanded 200+10 games or so. And I keep getting 2nd which basically gives u ur money back (u get 300 and entry fee is 200+10). I think I need to be more aggressive and bust more (ive been playing super tight until the blinds rise) to build a stack for the HU. I mean 1 win pays 700. But right now I'm focusing on hu play. I don't think those shorthanded games are very good for turning a profit though (I do better with the 200+15 10player games on party)...the players have been quite good, and with my tiny sample size I'm slightly -roi. Not to mention the fact that they start once in a blue moon. But it's good practise if you can break evan (and that's a big part of why I'm playing these).
Do you think it's possible to maintain 3/5 hu wins? Anyone here do it with a decent sample size?
