As I mentioned above, I just got the Airhawk Cruiser Medium on my Gen II. I got the Airhawk from Aerostich along with some other stuff. After about 50 miles I think I don't like it. It is quite comfy and maybe I'll get to like it on a longer ride. What I don't like is the way it responds to shifting body position. When I shift my weight from one cheek to the other, like when putting a foot down at a stop or when cornering, the Airhawk has a lag as the air moves through the air chambers from side to side. I find this feeling unsettling. The instuctions are clear about over-inflating the cushion and I gradually reduced the air until I was barely bottomed-out (pun?) when sitting straight but when leaned to one side, the air moved out from under. I just never got used to the feeling that I was attached to the bike by a slow-acting rubber band. I'll give it another try but in the meantime I have been using it as a lumbar support in my favorite chair and my wife likes it in her car.
BTW, I tried a gel pad on my last bike and didn't like that either. Like sitting on a slab of liver. So maybe it's just my super-sensitive cheeks. Sorry, no pix available. :huh:
