I wouldnt play loose if I were you... you won 8 in a row playing loose? How loose?
IMO, best strategy for DON SNG is to sit tight early doors instead of bleeding off 10-20% of your chips trying to see flops...
Then later on you can get aggressive on the bubble...learn when to shove and who to shove against.
Shove in position against the medium stacks, the ones who think they can just ride it out and cash.
Also, shoving from the blind when you have limpers is another good option, as late on, people tend shove if they have a good hand, and fold if they have crap... they may limp wih KJ KQ J/10 or a weak ace, and if you shove, chances are they will fold...(assuming you have been watching their play)
Thats just some thoughts from me
