The reactions to what I had been taught have been funny.

Yes, I use my rear brake as my primary brake. I do use my front brake, but only after I've applied my rear one and only if I really, really need to stop Right Now. I've never taken a header because of it, nor have I ever been in a wreck for stopping this way. I have been in wrecks where footballs were directed at my front wheel, or I hit some pothole or a curb funny. But never anything from how I stop.
Do you guys take Sheldon's stuff as bible? He's very good, granted - but I view him as simply one source of information.
