It has been very enlightening reading all of these posts!
I have always had my front brake lever on the right, and it is my primary brake.
I have not applied a lot of analysis to it, I learned to ride on a bike that came setup that way (1972 Raleigh, made in Britain, not as an export model), and each new bike since then has been set up to match what I was used too. My brain is too old to learn new stuff now, so I just keep using the same configuration. - A few observations after reading this thread -
1) I always signal turns with my left hand.
2) I always enter turns with my right hand on the brake lever, often applying some braking force, but rarely a lot.
3) When braking hard, I tend to apply front brake, with some rear, and shift my weight rearward. My bike usually has rear panniers on the back, so there is weight back there anyway.
