The easy availability of the Centurion also makes a refitted Talos a hard sell. The Taurians build Shadow Hawks, Griffins, Marshals, Clints, and Phoenix Hawks, and also have access to Starslayers and more mediums (and I assume either they or the Calderon Protectorate are rhe source of all of the Hatchetman 5S that suddenly appeared everywhere in the Periphery, because Steiner and Davion have moved onto other variants.) If they want an Omni Talso, the Avalance would be the best start to draw from, since it has Endo Steel and no expensive engine tech. I'll see what I can come up with over in the Fan Design forum. I do know the popular BTA 3062 mod for HBS Battletech has an upgraded Talos in it.
