As the title says...if I just stay married to my Silver B which I think I will, any recommendations for stainless grates as an upgrade? I am running some cast irons in there now (honestly can't remember if they were the porcelain covered ones or straight cast iron but I recall I bought a Weber branded product). Want good heat retention and sear marks which I believe you can still get with some good quality rods rather than stamped stainless steel
