there would be about $380 x average # of players in the December prize pool. about 38 weeks @ $10 a head per tourney. (assuming you play all weeks)
6 x $380 = $2280 -- seems unnecessarily high for $20 weekly buyins, IMO
maybe just hold out $3 out of each tourney buyin?? That would be about $500 and there would be left in for the weekly tourneys.
[end gratuitous use of computer calculator]
I like the buyin final event (with money added) idea.
Maybe if you play in a certain number of weekly events you get a reduction in the buyin to the final, and if you win a certain number you get in free, thus rewarding consistantly good players.
Also, you could have a higher buyin for anyone who has not played in other events, but who want to play the final.
I would suggest you pay more spots in the final though since everyone will have tied up a bunch of money in it over the year. 4-5 maybe??
Sounds like a fun idea, where are you playing???
