I was thinking the other day. To bad you did not make more rounds. Right now there are 34 projects. 34 is number that discourage people to check all projects and that way miss the good ones.  If there would bve secodn round where would come top6-10 projects then case would be different. That there would also be more chances to pick the right winner.
Just something to think about if you plan to organize something like this in future again.
