The current CTD's generally need an improved or custom compression tune/set-up - ie: increased rising rate as otherwise they do tend to blow through travel such as you are experiencing, we have used Jaytech and MOJO for custom tunes based on rider weight and riding style/bike set-up. I don't have direct experience of LoCo's tuning work or others such as TF Tuned but i'm sure they are are equally as good going by reports on here and other forums.
As for the comment regarding rebound i stand by it, if your rebound was working to such an extent that the forks reacted or kicked back violently then at the very least that will lead to a loss of traction on the front end, especially when banked over at speed which would either result in a faceplant or loss of control.
We try and offer advice when setting a FS up for folk and we often head out for a first ride wi them as the 7stanes trail at Dalbeattie is only 20mins away from us - once the air pressure is set up and we have the rebound where we feel the fork is tracking correctly all that's left is to show the customer what the other modes or settings such as climb/trail/descend are for. I'm all for Fox trying to simplify the variable modes but i feel they dropped the ball slightly with the 2013 range of CTD equipped forks/shocks.
