Also should note that overall specifics are not yet set, the "first one back" may not have all the 'standard' rules associated with it like the "bonus" corals.There are three categories of corals. Ultra, Bonus, and normal. The BoD will post a list of Utra and Bonus at some point. If you bring multiples of three bonus or Ultra corals you get to participate in a first "Ultra" round and/or a second "bonus round." After that rounds are normal and all get to participate. You'll note that people bringing Bonus and Ultra bring three. The they get to pick one coral in the special rounds. This leaves a lot of ultra and bonus corals for everyone down the road, and gives people a chance to get some truly nice stuff.
Also there was one frag swap where we put stickers on bonus/ultra corals, so they're at least easy to spot for those who bring them and get into those "exclusivity rounds" I don't see why that can't happen again. So in that sense there is a "high end section" they just are mixed amongst all the others.
