Risk or stay?

[ClaytonN]

I'm used to the 11's/22's structure of PartyGaming.

Now I'm moving my money to Stars. The highest I'm used to playing there is 15+1's, turbos. I averaged around a 10% ROI at the 22's and a 20% ROI at the 11's, both over samples of 500. Still on the small side.

Anyways, when I work off the $150 bonus PS is now offering, I'll have ~$900. Highest I have experience in is 22's on PartyGaming.

33 buyins at the 27 turbos, or 56 buyins at the 16 turbos?
I am relatively cluelesss to the difficulty of the games which is why I'm asking. I'm also getting a barometer for how risk averse you guys are.
