Can't believe I am even saying this, but I would go with looks. Tricked out Victorys are few and far between so I am thinking this will give you the most bang for the buck, which often = satisfaction.
Performance of these bikes, for what they are, is really at the top of the class with the few minor changes you have already done. Although not comparably expensive to doing up a Harley, once you start getting the extra oomph from the cams, my fear is that the sickness will take over and all of your extra money will go towards "just 2 more HP and I'm done." So in the end, you have a bagger that no other bagger can ever hang with. Kind of like taking a F-18 back in time to dogfight in WWI.
