Looks great! I went wit the standard hinged grates when I had to replace mine last summer and haven't regretted it once. Granted, I have always wanted the cast iron ones, but I haven't lost any sleep at all over it.
I did just pick up an Akorn recently that has CI grates. They are not as easy to keep clean as you might think, but I just get in there and clean 'em up any way with some little brushes, and religiously oil them. This makes me wonder if I had two kettles side by side, one CI and the other not, which one would be my go to unit. I have more than one kettle, so I assure you this will be tested at some point, but for now I really see no reason to feel lacking in any way over the standard hinged grate on a kettle, whatsoever.
