While researching my Royal Enfield purchase, the Classic and the Rumbler were the main candidates. What sold me on the Rumbler (same bike as the Thunderbird in India) among other items was the type of handlebar. It raises up much higher than the Classic, making for a more natural angle for folks (or at least myself) with longer than average arms. After two years of use I'm considering swapping out the handlebars for a set with the same height but different angle on the grip part, preferably with a cross bar where mounting my camera and/or cell phone would be easier. Time will tell.
As for braking, riding the Andes has me using my rear brake more than the front while maneuvering steep downhill twisty roads. Various reasons, less likely to lose control due to unexpected patches of soil on the pavement, not much braking needed when using the engine as a motor brake so no call for heavy braking most of the time, it guarantees the front brake is not going to overheat and fail right when one DOES need more braking power. The rear disk brake on the Rumbler gives plenty of slowing power when needed and is another reason the Rumbler was chosen over the Classic.
As mentioned above, stop by a vendor that has different styles of bars available. Try adjusting the angle, not just the height. And check the position of your clutch and brake levers, that also has an effect. Another thing to check when looking at different bars is the angle at which your wrist is bent when gripping the bars normally. Some handlebars are sticking straight out to the side, others are angled slightly back, some are angled almost vertical. Try and see if you can find a set that feels more natural to your wrist and hand position with less strain on your tendons to maintain position.
