Alan, I’m still new to the WSM but not the IQue 110. I agree with you about that bolt. It’s just too long so I sawed the end of mine off and I like it much better. With regard to the placement of the probe most of my experience has been with the Weber kettle and you could put it almost anywhere. However, with the WSM it’s a little trickier. It needs to be away from the sides where all the heat is coming up but not too close to the meat. Like Bruce I bought a probe tree and I think it gives you more options since you can stack your probes but you still need to place it as close to the middle as possible and at least an inch or more from the meat. Finally, I did get one of the 3/8 inch grommets since I have the ET732 and drilled out one of the top grill strap holes. It’s large enough to allow me to run at least three probes through and there is very little smoke leakage. But I still put a small piece of heat resistant tape over the grommet and run the probes through it for a little tighter seal. You now know all of my tricks regarding the IQue 110. By the way, I did use Nomex tape to seal up the entire smoker and I close all of the dampers execpt the for the top which is only slightly open. That way I just let the IQue 110 do all of the work.
