Thanks for the advice. To answer some of the comments: Yep, brakes are set up right with minimal clearance to the rims. Other than drum brakes there are no better options for a 35 year old bike, so I am sticking with the current set-up. Shifting is not an issue since I do that with my feet (2 sp kick back IGH). Hand strength is one thing but I think it's more about how your brain prefers to signal on hand versus the other. So I always use both brakes but in an urgent situation I reckon that my right hand is getting the message more than the left. Anyhow, I have decided to do the switch this weekend and see how it goes.
