Stainless flavorizers are the only way to go. I got this set from that big shopping site. They're the right lengths and quite thick:Here's a question. What's the difference between cast iron and stainless grills, flavorizer bars, etc.? Why do some elect stainless?
Now the grate thing: there are stainless, cast iron, and porcelain coated cast iron. The grates in my Genesis 3000 were porcelain coated cast iron, and I believe that was standard on at least some Genesis models for a period of time.
Stainless are fine. Cast iron are fine, as long as you understand the seasoning and maintenance (which anyone with a cast fry pan should!) Between them, toss a coin — either works pretty well.
The porcelain coated CI are a different thing entirely; they're fine as long as the porcelain is intact. A chipped one will rust under the porcelain and cause more loss. Personally, I'm not at all keen on having porcelain slivers in my burgers, so when the coated grates on my 3000 showed some porcelain loss, I replaced them with stainless.
