Hmm, I think there are merits for both structures. Having a single round of the ten winners seems like the easiest and most logical way to do it, and preserves the format/timing of the previous rounds. Clear, simple and decisve, and takes less time than the alternative.

The semi-final/final thing looks fun. It is a bit more fiddly, but might be more interesting and produce a more nuanced result. And who cares about taking a little more time?

I'll happily participate either way, but if forced to choose, I'd go for the semi-final/final structure.

PS thanks again Porthos for organising the Stick Awards!
