I'm pretty sure cardrooms do it for that exact reason, to minimize the payouts. I think at one of the online sites, you have to have a minimum of quad 8's to qualify. Otherwise, they'd face the same problem I was trying to avoid, paying out the jackpot all the time before it ever reaches a decent size.

For a one time deal as a sort of bounty, I suppose just using one card is fine. Like vanquish said though, I think it's kind of weak when a guy gets rewarded for playing K6o when the 2-3-4-5 hit the board to make the straight flush.
