What I can say about the RY bridge is that it is great for anything rock. Period. In general quite versatile.
When it comes to metal...that is a matter of taste. I have Tiny Terror Amp and a Fullbore Metal Distortion Pedal. I think it can do nice metal tones, but if I had to describe what I can get out of it with my equipment that is, it has more of middy In Flames kinda feel too it and less of a modern metalcore-esque Heaven Shall Burn or KSE.
It can do metal, yes but not really that very scooped, ultratight hifi sound. It has always more organic dirt and warmness about it, in a way Iīd say charakter or heart. This might be what your looking for.
As said, itīs not a modern metal pub. But if you wanne do blues, rock, power metal, melodic death,...it can do.
Short said: Itīs in the way you like the mids. Yes this is a bright agressive thing and all, but notice that the mids are where the agressiveness, dirt, warmness and overtones mostly are.
Thats how I see the RY at least. Keep in mind that is in my guitar, with my taste and ears and my equipment.
Only a guideline.
