I posted this in another thread: To DCT or not to DCT, that is the question.
I got the DCT because it seemed that the overwhelming reviews I watched and read said that for the intermediate/advanced riders the DCT was the choice at the end of the day and only the pro riders stayed with the manuals for the off road stuff. As I'm more in the intermediate camp it seemed like a good idea. You don't have to play with friction points or keep track of what gear your in (even with an indicator I'm still always counting in my head), with the DCT you instead get to focus more on terrain, throttle input and balance. I've ridden some wide single track, some mud, some gravel roads and it's been amazing.
The 'hard' part is figuring out what setting combo works for you depending on your terrain. So for gravel I ride S2, G, Abs off, TC 1. Suits my riding style right now well and the bike does everything I would normally be doing with a manual shifter. I don't use the paddle shifters too often or manual mode too often either. I usually just upshift manually if S2 is hanging onto a gear and my gravel or dirt road is just a straight for a while.
On the street I usually keep it in D (60mpg ftw) unless Im putzing around town then I'll stay in S1 or S2.
Where DCT really shines is the slow speed maneuvers. I took a local MSF advanced rider course a few weeks ago and the rest of the class were amazed at how easily I went through the exercises. Only having to focus on throttle control when doing sharp esses, wide staggered slaloms, or figure eights makes the bike so much easier to handle. I came away from that class with a perfect score and looking like I had been on the bike for years when in actuality it wasn't until the end of that class that I really started to feel comfortable on the bike.
DCT wont make you forget how to ride a manual bike. Decades of riding just makes that a muscle memory that won't go away so I'm not worried about that. I am worried that my next bike might not be DCT though...the technology is so good I don't want to ride anything else again unless I have to.
