Scott, unless you are buying the bike as a garage queen/show bike or investment, just get one set up they way you want it. If you want 4-speed, get it. If you was five geers, get it. After all, you are probably getting the bike to ride it, and you have to be happy on the road.
I got the AVL becuase the engine had the upgrades that I might have done myself. I liked the looks of the old-style delux much better. I wish they would have come out with the classic AVL series earlier. I would love to have an iron engine too, but I ride a lot and the roads in my area are not suitable for any bike that can't easily cruise at 65+.
I had to make some compramises in favor of riding. If I lived in an area more suitable to twisty back road cruising at 45-55, I would have gone with the older design.
