IMO the difference between a WSM and a UDS is minuscule with the exception of Price. A 22 WSM is going to be pushing the 400 dollar mark, a 2 rack UDS will run you about 150 and give you the same cooking area. Allot of beer & weenies can be had for 250.
If I was going to make that move I would save up some extra coin and get a BW party It gets cold in your neck of the woods an insulated cabinet is a nice thing when you need a team of huskies to get to the pit.JM2C YMMV
