Yeah, I was thinking along similar lines to what Dats said

In olden days, before Black Friday, at certain sites I won't mention, the rebuy/add on tourneys were pretty enjoyable, and the structure was pretty sane. For some reason at some sites I won't mention, rebuy/add on tourneys have really gotten into some wild structures lately. They probably can be profitable if you can figure them out and don't have a headache, but you probably have to understand the structure very well, and be willing put a lot of $$$ into the rebuys and add ons. It looks like under some of the current structures a player is liable to get blinded out unless the player rebuys or wins some nice pots.
