That is awesome. Do we call it the flying taco handle?
You do some grate work!
Re tel tru: I would test the accuracy of the Weber therms. I used to not trust them and they were basically dead on when I tested a few. Many, not sure about Weber, have nuts on the back to adjust them.
I used to get tel tru for all of mine. They may be a little better, but at the end of the day they are still bimetal in a poor location.
