moving up from 10$ to 20$ HU SnG

[vodoo]

hi guys,

i was thinking about moving up.

I am 4-tabling HU SnGs (10+0.5$)at the moment.

And i was really crushing them.

So do you think that the 20 s are harder?

Because it was really easy to move up from the 5$ to the 10$.

i have about 1600$ in my br so im rolled for them already.

Is it still possible to be a winner @ the 20s by playing solid, not bluffing much and playing sth like ABC Poker?
