Here's a pair or 21's, both WS-1 and WS-2. Top is a 12, 26" Flatside. Bottom is a 20, 28" Skeet.
While not Parkers, they've yet to embarrass me on a Skeet field. That being said, I think Parker (Remington) truly nailed Skeet chokes with their Skeet In/Skeet Out constriction combination. Really right on for the game, much more than WS-2/WS-1 (L.Mod/Skeet).
