I'm really liking the Progressive 418's I have on mine, the adjustable damping works great.
I had the 440's on for a couple weeks and didn't like them as much as I thought I would, so I boxed them back up and exchanged them for the 418's.
Just shot off an e-mail to wide open customs to see if they'd be interested in doing a fairing up for us.
Mentioned the problems some have had with fit, finish, and of course the price of Corbins.
When I hear back, I'll post it.
