My group are mostly casual players with some more serious players mixed in. The tournaments are $20 buy ins with 1 $20 rebuy allowed in the first 90 minutes or a optional $10 add on at the 90 minute mark for players who have not used their rebuy. My question to the forum is what are your thoughts on offering a optional $30 buy in that will include a rebuy/add on chip. It would be a deal for the rebuy but commit players to use the addon. I average 8 players, 1-2 rebuys and 4-5 addons.
