I personally wouldn't go that wide again, because you do feel the difference of a 650g tire and unless my imagination got the better of me (which is possible) even the width made a big difference in the wind. I probably will try these in 700x32 some time and maybe even 700x35 (which is curiously listed as ERTO 37-622 on the Schwalbe USA site).
OP has already ordered his 32s, but just to chime in, I'm riding 700x50 Supremes right now, they've got about 3500 miles on them and seem like new. They were pricey though, if I had it to do over again, I'd try out Schwalbe Hurricanes.
