Unless the pack has some sort of saftey discharge curcuit in it (small electrifly lipos have this IIRC) I see no reason not to use the mail leads for the charge while balancing thru the tap. I will say that most balancer leads are twwo small to handle more than 2 amp charge rate. Any more and the connectors and wires may melt. So you have to use the main leads to charge the lipo, if you want to go over 2 amps. I charge all of my lipos (inc fp) with a charge thru balancer that uses the main leads and the tap.
