I've had my 1100 for a few years. ONce in a while, I contemplate another ride; just can't seem to ditch it, though. Hard to describe. . .sounds cheeze; but some bikes have a kind of emotional feel to them; others are just bikes. The 1100 definitly has the former. I rode the 950 and the 1300 -- they are like the latter. Very comfortable rides on both - they remind me of my buddy's C50 -- a bike you could easily ride for a while and be so comfortable that you say "wait a minute. . .what were those last 5 miles like?" cause you just zone out. They just don't have any unique appeal at all (for me, anyway). There are times when I'll ride a bike and realize I like riding. There are other bikes I'll ride and think to myself, "Self, I love riding this machine". I didn't get any kind of 'kick' out of riding the 950 or 1300. Though the 1100 handles like a pig at slow speeds (not as bad as the roadliner) I like a bike with a unique feel. Other than the slow speed stuff, a great bike. Every mechanic i've talked to loves them too, and all tend to say they'd take the 1100 over the others in the lineup anyday.
Having said that, many love thier smooth creature comforts, and the modern niceities of say. . .fuel injection (don't have it on my 05), a gas guage (not a huge deal to me anyway) and liquid cooling (never saw the need on a cruiser). I like that the 1100 seems almost like a throwback bike. . .and I like the look of the custom -- it just exudes cool.
But hey, they're all nice machines. whichever you wind up choosing I'm sure you'll be happy.
