I've been thinking about the TV, my concern is, will I be disappointed with the decreased power?
That is a personal question. IMO the TVL has ample performance for a touring bike. I ride one up with luggage, the bike itself is not grossly overweight. The KTM and Ducati have more giddy up for sure.
Test ride one, after eating a couple donuts and see for yourself.
