I would prefer you to have TB .DS is a killer ,but the pressure these classic style bikes put on your hands in the bumper to bumper traffic is huge.
Since you are in Bangalore, I recommend TB,else just go for classic 350 which will give you a better mileage since you will be travelling with your back pack only.
DS is not a choice in the bangalore traffic.
The ergonomics and the raised handle bar in TB will be relaxing for you to ride.
Just FYI ,I ride my classic 350 with wrist support.
