Mmm....I know that more contemporary thinking favours "long and soft", but that .177 of mine which shoots so nicely has the V-Mach kit. Virtually no spring proud of the cylinder prior to pushing the end block home, so hinting at a shorter / stiffer spring. It's one of the really early ones with the factory muzzle weight, just stripped, de-burred, Dri-Slided the cylinder and fitted the V-Mach kit.
