Just speaking for myself, I'm not entering doubles because it's too expensive. $20 for transit+singles+venue is already twice what I should be spending a day (and for students as well). I don't think singles should be lower, because ****, there needs to be some money on the line, but the doubles tournament is so stacked between 1 or 2 teams that there's not much point in anybody else entering. I'm pretty sure I can do top 4 in singles, but there's no point in me entering doubles because I don't have a partner good enough to get top 2. Obviously it's not expensive, but it is for all the new people we're trying to get into the scene, and I don't think there's a lot of newbie teams who are going to want to give Ben and Eric $20 each just to get knocked out within 2 or 3 rounds of brackets. You might as well just ask them for $10 money matches.
