A few thoughts from the trip, I bought these earplugs from amazon, and they are amazing. They do such a good job of blocking wind noise...I took a handful of them with me, but after a couple of days, needed new ones...I tried everything in the states(CVS, pharmacies, hardware stores...etc etc), and none were close in terms of quiet.
Also the nelson rigg sportbike tailbag deserves an award, I tried to travel as light as possible, but still had a bunch of stuff, so for 11 days I abused and overstuffed that thing, and it performed very well...
I've also found my 'happy settings' on the AT...with the preload cranked to max, and damping set to the sportiest settings...the bike is way more composed and controlled, in the twisty stuff, but also around town and in urban environments...its not so unwieldy/wallow-y anymore.
Having the seat set to low also helps tremendously with confidence in urban riding.
