Tony, I put a Darkside tire on My FJR for an East Coast trip in 2015.
I spent most of the time on the slab and the rear tire was perfect for that, especially in the rain.
Allen C, Cav47 and several others took me riding in Southern Indiana on hot afternoon and the Car tire was real work hanging with those speedsters.
The "difference" is that you have to keep pressure on the bars while turning. It also feels weird in the parking lot.
For the ride you are looking at the Car tire makes perfect sense.
Garage space, lift, Oil Change and tire machine and balancer are all available at SD I-90 Exit 14, I'll even do the work while you catch some zzzzz's and SWMBO might even feed you.
Let me know what dates you are thinking about.
John
