I'm up for whatever NDN and whoever else is organizing this wants to try.
I personally think that two 5 man teams would be more profitable if we're sticking to 100ish person games. 300+ tournies would be fine for ten I think.

I also agree we should give 100% back at least for awhile to build the pot. We're all profitable players on our own but when only half the winnings go back its a lot harder to make money for the pot.
