I don't understand the abject fear of going over the bars if using the front brake. Braking isn't a binary trigger. There are infinite possibilities between "on" and "off". I use the front brake for all stops. By using the front brake for everything, I know what the limits of braking are relative to traction and/or ending. In an emergency, I can supplement using the rear brake, knowing that even if I grab way too much rear brake, it isn't going to compromise me. In these stops, 90% of my attention is on the front brake. If a wheel stats to skid, I ease or the brake until it starts rolling again. For maximum braking force you keep the wheel you are braking with on the verge of skidding.
