For those of you that are having problems gripping your deans plugs;

Never had problems with the deans. I have seen people use a little graphite on them or dielectric grease (which you can find at most auto supply stores), and it supposedly helps. I've also seen people that have drilled a small hole (not very deep) into the side of each connector to accommodate snap ring pliers for separating the connector. Guess I've just been lucky with mine so far.
Also, soldering deans connectors is a whole lot easier if you've got a really, really, hot iron with a large-ish tip. A whole lotta heat, in and out fast is the way to go. I never solder with less than a 45 watt iron.
The traxxas plugs seem decent enough I guess (a little bulky though), but it seems to me that, a plug with a connector that snaps into a holder will eventually become a plug with a connector that snaps out of a holder. Who knows, they may turn out to be the best thing since sliced whatever.
As far as adapters someone mentioned, I do a lot of testing stuff at work so, I've got a box with every possible combination of plugs and they sure do come in handy.
