Agree with you on the balancing connectors. As computers have gone to USB, ethernet plugs, etc., it would be nice if we could be so smart...
Not to create a Traxxas vs. Deans plug debate, but the Traxxas plug is very nice in the way that it is 1)easier to solder, 2) doesn't need shrink tubing and 3) is a lot easier to pull apart. That said, all of my stuff is Deans. Why? Because I started with them and it would be a pain to convert everything now. Plus, everyone else uses them so if I need to borrow a battery or a charger, I know I'm covered. Booo choices!
