Im thinking that you would probably get on best with either the Nailbomb or Warpig. The Nailbomb has a full midrange and a old school metal tone (early sepultura) the Warpig has more sturated gain and a bigger bass response. Both would do what you want well, its just deciding wether you would like to go for all out blistering metal or go lower gain and have more versitility.
