If the Optima indeed does'nt come with the Bergara Barrel then I'd pass on one and opt for either ACCURA. Now I personally have nothng against Knight or TC, they make a very good MLer. But for the Price you get more MLer for the Money getting a CVA.
For me besides the cost the SS Bergara Barrel is what sold me on the ACCURA, the TC Triumph has a Standard Steel Barrel. For the money you spend on a TC Triumph it should at least come with a SS Barrel, if it did I might just own one.
