ive got a stumps stretch.
no spacing issues with this one.
i'd probably need to take out a rack to do a turkey, but i'd use my wsm for a turkey.
i use my stumps for butts and brisket. i couple it with a cyber q and it's all over but the shoutin.
i cant speak for the superior, but im sure theyre pretty much the same. i've heard the guy from superior used to work for stump and he left and started superior.
either way ya cant go wrong. efficiency is the big deal with these.
get one bigger than ya think you'll need for sure!
good luck to ya
