I'm not quite near 64, but I'm no spring chicken. My nickel's worth of free advice would be this: Find a dealership near you with a DCT on the floor that will let you test ride it.
I just bought my DCT 2 weeks ago. I insisted on test riding it before I bought it, and I'm fortunate that the dealership readily agreed.
You WILL instinctively grab for that clutch lever the moment you get on it. It will take some getting used to. You'll have to re-approach slow-speed maneuvers now that you don't have a friction zone to leverage.
That said, you'll find quickly that other things present themselves. Engine braking and throttle control (and rear brake) replace the friction zone. You no longer have to worry about being in the right gear as you decelerate or stop at a light. It is impossible to stall the engine (though, I bet, at some point I'll discover a way).
Having the DCT means you have one less thing to manage as you ride. I think this fact gets overlooked in the arguments about having to relearn things.
And don't get me started on the "real bike" bullcrap. I've heard this crap about every other advancement in motorcycles (ABS, linked brakes, rear disc brakes, EFI, rear suspension, gear-driven engine to transmission linkage instead of chain); it gets to be a bit ridiculous. What someone considers "a real bike", as you might imagine, tends to be biased towards when one started riding and the influences they've had from others. Sad, really. I love my DCT. My passenger loves the DCT. Anything that enhances the overall riding experience and lets me spend less time managing the bike and more time enjoying the road and the scenery (my personal preference, granted) is a good thing in my opinion.
And that is my opinion, for what it's worth.
