I've been looking at these, but what do you think about the payout odds? It seems a little lop-sided to me. You get 20% of the prize pool split between the 4 games, and 20% split to the overall placings. If you win all 4 games, you end up with 50% of the prize pool (same as if you'd played just a STT). It seems it'd be easier to just win one rather than all 4...
A couple things, tho:
1) If you registered for 4 sit-n-gos at the exact same time, what are the odds you will get a seat with the same 8 opponents? Virtually nil. In the matrix you will be playing more hands against all of them, and will be able to get better reads on them quicker. In addition, I'm sure there will also be a couple players who aren't good at multitabling, or at the very least can't do anything more than play mechanical poker with 4 tables up - this is very easy to exploit.
2) If you win all 4 tables, you are a Dominatrix (hehehe). As a result, you win the entire prize pool (and not just 50%).
