I just put Chromes on my ceramic 2006 Stingray 5 (H). I've only had them on for a week or two, so I'm still waiting for them to settle in more before I make any broad statements, but I was very pleased with initial results.
They're probably a good bit brighter now than they'll ever be again, but there was no mistaking the tone for flats. For instance, I told my drummer that I had made the swap, and he made some comment like "eh, that's mostly a feel thing". I LOL'd, plugged in, hit a few notes and looked at him - and he promptly admitted how wrong he was.

So even to my drummer's less trained ear it was a noticeable difference.
Here's the thing, there was less zing, and less sustain as you'd suspect, but there was this amazing mid-range punch that was all the more prominent for it. Maybe it's because it's, you know, a Stingray, but it was still a very aggressive tone in my hands.
We'll see how long it stays that way as the strings mellow out a bit. As for now, I'm a big fan.
