Sounds like you need an RG1527.
I wouldn't look anywhere else. The 2008 and up models in Royal Blue are my favorite guitars in the world. They play SO smooth. I learned all bits of shredding I know on one.
But Lone has a good point. For your tuning, get an RGD2120Z. You don't need the slightly longer scale for it. It just is an awesome feeling axe! Then get some SUPER thick ass strings on the top (62, 46, 36, 22W) and some normal ones on the top (14, 11) and I swear on my life, your shredding will cut through the mix, and your lows will be SUPER thick sounding.
And I know those strings sound thick, but they're not that bad. They'll easily be playable and bendable all day long!
Oh, and the RGD2120Z came in two finishes. Matte black on the mid 2012+ models and this cool silver crackle finish on the 2010-2012 models. If you want that, you may have to go used.
