You probably know this, but a word of warning in case - the pro elite has huge power potential and is designed to run over 20 FP, well above the 12 FP limit, so make sure you have a chrono to hand, and expect to have to chop the spring a little... Spring length is a very poor guide of overall stiffness / energy, as the wire guage has such a huge effect. FWIW I prefer a less stiff, but still fairly long spring in these, i.e. 3.0mm wire. the 3.2 or 3.4 wire springs are stiff and difficult to get under 12Fp and still shoot nicely.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
