a) I have the smaller Triton, but I believe it's the same mounting/bolt pattern
b) I have the Black Dog plate, not Rockler, but I'm pretty sure they are the same, just different colors
Otherwise, the same
Anyhow, I didn't have any trouble mounting and/or using it. I've had it for almost a year with the router mounted almost the entire time and don't see any sagging (just checked with straightedge).
The bolt pattern is such that you have a limited number of places that you can put the winder (crank?). I had the hole 180* from the fence, which gives you the most flexibility to make minute height changes if the bit is "buried" in the fence. The difficulty is that the switch is then located around back; not a problem if you have "shimmed" the switch _on_, although I didn't.
I'm currently working on improving under table dust collection and my self-designed construction required turning the router 90* which ends up placing the switch and height lock in a more convenient location and has the added benefit of placing the hole for the winder nearly in line with the bit so the dust from blind cuts like dado's will just be sucked downward.
Anyhow, to your question: I might consider a different plate if I was replacing the BD, but I really have no serious issues.
