What to buy, what to learn by?

[glass_onion]

I've been reading the hell out of whatever I can find about O8 and jsut started playing money. I seem to do pretty well at the casino $3/6 with 5/9 players seeing teh flop, athough I seem to have tremendous variance relative to when I play holdem, which is for the most part a slow trend upward. Since I play extremely tight and only rarely imploy promotional raises - mainly only doubles - I wonder why that might be.

But then again, I have a lot to learn. WHich brings me to the point. After reading Cappeletti's "how to win at O8" book I was thinking of investing in some playing software, perhaps off of Mike Caro's website. Does anyone currently have any of this software? Anyone want to review it?

I would be prettty interested in being able to simulate types of opponents and being able to play hands against them, and having a general tutorial/simulation session.
