Most everyone seems to be on the same page, nitpicking notwithstanding.

I cannot get too "fast" in grouse/WC cover, IME. Butt-heavy is not the same as fast. Light is not the same as fast. Thanks to Rocketman for finding a way to measure and quantify fast.

On average 26" doubles are faster than 30" doubles. Yes, I know you can find fast and 30". They are more the exception and, often, quite pricey.

Have a 26" Miroku Daly that's pretty fast, but a couple of 20 ga M-21 skeets in 26" are even faster.

Don't know about the wild west. Suppose a 391 sport would be about right...........
