Jeez, watta woman. . .watta bike. .watta pillion. . . but back to reality. . .I had a small Airhawk 2 pillion pad for when I road my kids on the back. I tried it on my seat and the air pockets are larger and softer but it's small and no center groove. The Freedom Air has very clearly shaped air pockets that actually seem to work better more pumped up, compared to the Air Hawk, where you just had to put in a tiny bit of air.
Just rode my 25 miles into Chicago with the Freedom Air. Definitely more comfortable, less vibration and you feel the shaped back air pockets against your butt and sit bones. But not "cushy" like the Air Hawk. All in all, considering that it's the only one with the center groove, and the only one that looks like it fits the R12 really well, I think the Freedom Air Sport Seat (not the other "cruiser seat) is a good match for the bike.
