PRIME RIB!!!!!!!

[HardwareGrl]

As my Christmas hosting duties are fast approaching, it occurred to me that this would be a great place to ask advice on my main dish…….PRIME RIB………(this would be a great place to have a nice echo effect, maybe some glittery stuff, etc).
I love, love, love prime rib, and for the past couple of years I have been presenting my family with a BBQ’ed Prime Rib for Christmas, and I have been doing really good if I do say myself. BUT, resting on laurels is not allowed, there is always room for improvement.
So, does anybody have any advice or rub recipes for bbq’ing large cuts of beef?
For point of reference, I grill on a Weber Summit, and I use the rotisserie. Oh yeah, fun fact for Weber users, (and I had to really dig to find this out) a Weber rotisserie can handle up to 18lbs of your protein of choice.
