My current gain actually is quite good. MY dist/od units are mt-2,ds-1 and sd-1, I run them, mainly mt-2, through cs-3 -> eh-2 -> eq -> gp-20. The sound I would describe as almost Megadeth-ish and 80's metal which I am fairly pleased of. But I thought having an extra boost would help in the gain department and help in giving the distortion more ferocity. Something like what Megadeth has done in Youthanasia and Countdown To Extinction.
