Wow, nice rides. Were those cars in the 2009 Scottsdale auctions? I think I remember seeing them when I watched it, but could be wrong.
As to gear, I wear a textile First Gear Jaunt jacket and HT overpants. I go that route because I do lots of touring and long distance riding and need something weather proof. If you will be primarily canyon carving and sport riding in good weather, go with leather. Of course I also wear full coverage boots, leather gloves with knuckle protection and a full face helmet
