I don't see 9mm very often working out on a flip grill which is kind of a shame. I love my original 1st gen Summit grates (I believe they are the Weber 9930 that @Josh Dekubber refers to). I previously owned a set of "rcplanebuyer" Dave Santana grates on my Summit which I had bought without grates. They were wonderful as well, of course, but not really better. Plus, the ones made for the Summit include a "trap door" to access the optional smoker box that goes below the grates.
I have also had Qlimetal's 9mm grates which are technically a hair narrower than Dave Santana's. I can't see much difference in actual use, though, other than that Dave is confident enough of his welds to omit the central support bar that gets in the way of using a Chargon which is my preferred choice for cleaning stainless rod grates.
I think 7mm are very fine grates and all that most any purchaser of a flip grill would be hoping for.
