Honestly any setup can be perfect for Metal as long as the bass drum is 20" kick or above. I've tried 18 before and it sounds way too high.
My personal peference is Pearl. I've been using Pearl Exports since I started playing 14 years ago. I play Exports because every set I've had I've been able to tune eith ease and in the stuio and live can make sound very badass. Although you can only get Exports used now as they were discontinued for the Vision seriies a few years back.
Honestly above all else, I'd say go used. As long as the shells are in great condition and not cracked, they are perfect with the right drumheads and a knowledge of tuning.
If you come across any kits you might consider a deal, put up a link here and I'll let you know if it is worth it or not. I'm happy to help out in any way I can.
