I voted for light487 (not becuase he voted for me!)
In my opinion, everyone did a good job based on their levels of experience. My second choice was Equator with BarChordNick running very close too.
I chose Light's because of the overall structure of the solo. Nice flow from start to finish, a couple of parts were a bit off but overall there was a definite theme with a beginning middle and end. Tone and recording quality were my only real gripes but they come down to gear and personal taste anyway. Nicely done Luke!
