I have just wired up two seperate three-way switched circuits.  I used two of the new "Essentials" dimmers on one circuit, and it seems to working be fine. By fine, I mean, either switch can be used to turn on/off/dim the load, so it works like any 3-way switch would.

On the other circuit, I had only one Essential dimmer, and one "regular" C4 dimmer (the more expensive one they've been selling for years), so I wired them the same way I wired the other circuit.  I used the travel wire that was already part of circuit (I was replacing some older Lutron switches) to wire them both together.   I am getting some weird behavior.  I haven't seen a specific pattern, but neither seem to be able to turn the lights on/off reliably.   

Is this because I wired them wrong?  Is there an incompatibility between the two types of switches?  Give that they are C4,  can't I just wired one to the load and marry the other one to the switch with the load on it?  In other words, just use the software to make a 3-way switch?

I am fairly confused here.  Any help would be most appreciated.
