braid as leader with mono backing

just wondering has anyone tryed braid as a leader with mono backing surely with its thinner diameter it would be better and go cleaner through the guides but then also im probably wrong answers on a postcard please

There would be no give in it and it means casting with a risk to cutting those delicate fingers of yours.

see i knew there would be a reason, i will sleep tonight

Think you are right. The reason for the strong mono leader is to act as shock absorber if the cast goes wrong. Try a tapered leader if worried about line diameter? They are around 15lb at end tied to the main line and gets thicker up to 60-70lb at end tied to your rig.
