One thing you have to bear in mind is that a cut down spring could introduce some valve-lock at high summer temperatures.
Other than that its a win-win-win situation: less cocking effort, less gas consumption, less noise.
Such a comparison would prove very useful and interesting, evert. I guess temperature would also have to be an important consideration.

Re the weaker spring on the shorter barrelled 2240 (as opposed to the 2250 models), I wonder if the reduced muzzle blast may help accuracy a little?

Also, at what point may too weak a spring affect CO2 capsule piercing reliability?
