I don't play in many home games, so I'm not sure how many are KO format. But I did play a bounty tournament at a casino one time, which was pretty fun. The prize pool ended up being pretty small, since a lot of the money was going to the bounties. What's most interesting is the winner would get his own bounty plus 2nd place's bounty. Kinda cool. If your play style is pretty aggressive then you'll get a little more incentive for getting all the chips in the middle a lot, that's probably about the only advantage to this kind of tournament. At least if you don't place high in the money you get a chance of making your buy-in back just alone in bounties.
