New Years Prime Rib - Question

[smoking in ft. collins]

I am smoking a prime rib today per Bear's thread here: http://www.smokingmeatforums.com/t/110433/prime-rib-new-best-ever

It looks like a 6lb PR takes about 4 hours of smoking.  I have an 8lb PR.  Would that take about 5.5 hours?

Thanks in advance!

It's not about weight when cooking a Prime rib. It's about thickness and how done you like your roast.

If your 8 pound roast is as thick as the 6 pound roast they will be done around the same time.
