I am pretty sure the New Vaquero and Flat Tops are on the same frame and the Blackhawk and Super Blackhawk are the same size frame including the 5 shot Bisleys.
The exact opposite is the case.
Between the Blackhawk and the Flattop, all having the same barrel length I'd be surprised if there were more than 3 oz between all the guns. I have original Vaqueros and Blackhawk, and Bisley Blackhawk in 45 Colt. All are nice guns. Don't see how you can go wrong with any of them.
The major choice is convertible or not. There are some good loads out there for any of them. Even the lightest model will handle anything in North America.
