Only in extreme circumstances would I recommend using just the back brake. The object is to find the right balance of front/rear breaking force for most situations you are likely to encounter. It is important to not put yourself in a situation where you can't stop safely by carefully applying both brakes. If you're speeding down hill on wet pavement with a sharp turn ahead, It may be too late. Just don't go there.
Short of ABS brakes it's unlikely we can find the perfect front/back brake pressure balance, and that's OK. Just relieving the back brake of much of the work is enough to reduce skidding. With some practice we can probably get quite good at judging the right balance, Something I should be doing more of too. If you feel it's too dangerous to apply normal front brake preasure, Then error on the side of safety and back off.
