I don't think you'll go too far wrong with 'bombs. The neck is beautiful played clean, the bridge breaks up fast, but does a wide range from overdriven to metal. I've not tried it much myself but others have commented that it does well in drop tunings as well if that helps your cause.
The ceramic Warpig is surprisingly versatile, but personally I think it does best with a good amount of gain, if you want some serious bottom end chug without it feeling lifeless the WP will work for you.
The Nailbomb has a ceramic option for the bridge if you want it.
I hope the recording session goes well, and I hope you can post up some clips when you get the 'bombs loaded :)
