You could effectively dub those two contests as being the 'elitist' contest and the 'noob' contest. At least the way I see it, that's what people would do
That being said, unfortunately, I don't think that would solve the problem...
I personally think Darke should keep running the contest as is. As orlouge said, these contests are a great way for people with not as much experience to get 'in the mix' (pun unintended) with other, more established mixers. Which is an incredibly awesome thing, in my humble opinion.
If you don't want to listen to all the tracks and vote, or are indecisive about your voting, then...don't vote. Nobody's forcing you to vote.
