Tom,
Welcome, If you hang around here long enough, you'll find that a lot of these guys know more about bikes than the local stealer (I mean dealer). Not sure if any one guy knows all, but the collective minds here have thousands of years experience with these bikes (all kinds, not just CVO's).
IMHO, the lowered air ride shocks are the way to go if your looking to lower your bike. I've seen complaints on this site about the PS 440's topping out and clunking when on rough roads....can't really speak for them, but this is what I 've heard.
Good luck with the project, and by the way,,,,,I'm 6' 2" with long legs, and I like my bike lowered. Like the look, like the extra push while backing up.......don't even mind the stiffer ride.....
Go for it....
