My honest opinion Paul........your nuts to swap Centaur 2 for a Gorgar. You may never find another Centaur 2, but Gorgars come up 4 times at least a year just on ebay. Just keep it for awhile, if you find it boring then move it on. But if that Gorgar is good, and priced right buy it as well. If you have no room, take the heads off and put them under your existing pins.
