For the avoidance of doubt, my ideal springer at 12 ft-lbs or so would be a 22mm cylinder long-stroke late-model (LW barrel) Webley Tomahawk with a Venom trigger and a resettable safety catch, preferably ambidextrous. In walnut.

Which is basically the mythical unicorn Air Arms break-barrel that at least 63 people on here have been lobbying for.
