I've had one cell on a 5s pack be lower than the rest as well. I just put the leads of 1M ohm resistor (or any really high value) in the balance tap of the suspect cell and clip my charger leads directly to each resistor lead. Then, I set my charger for 1s and charge at 0.5A. Every 100mAh or so, I stop the charge, let sit for a minute or two, and check the balance. If I have a high cell, I do the same, but discharge instead. This is faster than the measly 100mA balance rate of my balancers, but you have to be very careful not to touch the leads together at any time.

As far as connector quality, I haven't had an issue yet. However, I always make myself some balance connector caps so that dirt/debris doesn't foul up the connector when running.
