Sweet videos Ben.
I almost ate it today, on 84, because of a combination of wet roads, slick tires and those small black road patches. My rear wheel broke loose when rounding a turn (~1:07 in your video methinks) and the bike got real squirrelly and at that point I started heading for the trees (!).
It was one of those moments that happened in slow motion, and luckily I didn't try to over-correct, and the bike took care of itself and straightened out. Needless to say I took it slow the rest of the way down.
