I guess as someone who just plain likes my Troll and is perfectly happy with how it rides, if the Sutra rides well for him and he likes how it looks, what the heck, sell the disc trucker and use the Sutra.
I didnt look into all the details of components of both bikes, but arent they similar or the same? Don't really see why it would be a downgrade.
and in the end, just ride whatever one you like more and get out there and stay fit and see the world on your bike, whatever bike--of course, if there are obvious things you'd like to be diff or "better", then identify them and figure out how to make changes.
I guess if a basic thing like frame size shape not working for you, and other stock bikes not working, then I can see going custom, but most of us can ride stock bikes with stem changes etc and be happy enough.
