I was trying to say that Weber went to the welded ones in the second generation. Although in the back, they are still exposed in the first generation Summit. I am guessing that some people did have premature failures because of steaks, etc. being cooked all the way in the back. I haven’t had that problem yet, but as I said before, replacing crossovers on a 1st gen is a lot cheaper than when those welded flavorizers fail on a 2nd gen.
