What is the brand of the rib hanger you are using? I assume you are happy with it. I've thought about getting one myself. I have a WSM, although its a 22". I don't usually need more rack space but occasionally I do.
And I agree, it is a beautiful day for smoking here in CO. I may fire my rig up in a bit, I have had 10.7 lbs or pork bellies brining for a week to make into bacon.
I have the LavaLock 8 rib hanger and yes I love it. It allows me to smoke more ribs and host more people.
