airhawks are brilliant, without a doubt. Me and the missus wouldnt have done our France/spain tour without them, and that was on a cb1300, which had a fairly well padded perch.
I had a fazer thou that we both loved, and went for a fz-1. Its what it is really, a flat barred sports bike. I tried a french 'comfort' seat, and it mullered my bollocks within ten miles. In the end I went back to a gen one. Its an old story, but sadly, its a true one for a lot of blokes. Just depends what you want out of your bike
