I really like my CVA Optima, But between those two I would go with the traditions. In that range, it is six of one and half dozen of the other. The main difference is that the traditions says it has a nickle barrel, and I love the nickle barrel as it is more corrosion resistant than the blued.
BUT I shopped around and found my CVA for 179.00 for camo stock and Nickle barrel. The same gun in Black / Blued was 159.00.
Also, the break action guns are much easier to clean and are very user friendly. IMHO.

This is the 500 Muzzleloader combo with a 24" .50 cal muzzleloader barrel and a 12 ga. 24" slugster barrel.
It is a great combo, and Mossberg is known for keeping prices in check...
Just a thought..........
Good Luck and God Bless
