Getting better but...

Hey all. I have progressed to the point that I can make it to the money at Sit-n-goes nearly 80% of the time. But when I play in multi table tourneys my same strategies don't work!?!

I think it has to do with table image. I can use my image and other's image to pretty much make it through streaks of poor hands and have been pretty succesful but that doesn't work in the middle of MTTs when you move around from table to table.

I'm not sure, maybe I should just move up in $ at the sit-n-goes and leave the MTTs for freerolls.

Any ideas?
