What a cool contest. I don't think the winner overdid it too much. There's a lot of pinch harmonics but I actually feel like that solo is just a less organized very of a Jack O'Shea solo. It matched up pretty well and O'Shea loves his pinch harmonics.
Love contests like these, the winning solo is killer and I really dig some of the honorable mentions as well. I need to keep a look out for these kind of things because I would have loved to give this a shot.
