Unlimited good for the House, unless..
Unlimited rebuys benefit the house, able to double up the entry fee, at the least. Question for the CC crowd: are there any tourneys where the rebuy fees are dedicated towards the winners, ITM, ie, grow the payout, where not all rebuys go to the house.?
Rebuys, have to know you are in a bizarro world, some auto-shove, because they know ahead of time that they will do at least one add-on and/or rebuy.
The time and patience required make me steer clear of unlimited rebuys, unless its a ticket to a tourney; or a step towards a satellite.
