HU SnG's - Suggestion for PokerStars / FullTilt

[NSM]

Obviously a rematch button is ideal for keeping a fish on the hook if you are so lucky. However, is this at all bad for the larger pool of players who don't get a crack at same fish? At times, there's not a ton of volume at the 50-100 levels, I'd hate to think there's a couple -30% ROI snappers who get pulled out of the mix while the rest of us have to -EV grind against each other.
