Before I get to my suggestion, I'll state that I feel the raffle items is top notch, and given the amount of items raffled compared to people & tickets, everyone has a very good chance of winning. Probably in most cases you get back much more value than the cost of the tickets. My suggestion is that during the raffle, what about putting 4 corals in a group, 2 SPS & 2 LPS, or 2 SPS, 1 LPS, 1 softy, for example, call out 4 winners for those 4 corals. Winner #1 goes up and goes up and picks from the 4, and while that person is choosing, winner #2 is chosen, picks one and so on until the 4th person gets the last one of that group. There doesn't need to be any waiting for someone to choose, if you're slow then the next person may go up and pick whatever's unpicked. I don't know if this has been tried before, or if it would be too chaotic, but the goal would be to make it more likely that you'll get a coral that you'd prefer. If you like LPS, you don't get an SPS and visa versa. If you're a beginner it's easier to choose one that's beginner friendly. This isn't meant to criticize the raffle at all (I've won my fair share), it's just an idea to hopefully provide some element of choice during the raffle.
