well I have 2 prometheus spring with absolutely terrible performance ( around 250 - 300 fps ) and 2 with good classic performances.
I spent months wonderwing what the fuck was wrong to figure out in the end that 2 of my springs were fucked up.They'd give terrible performance in any gun, creating jamming problems and such.
All other springs I tried ( including some systema and stock ones ) gave perfectly coherent FPS with my guns.
they were BNIB.
Aaaargghh !
so be careful.
