After about 500mm, additional barrel length does not really affect accuracy. It may give a slight FPS increase, but FPS ≠ accuracy.
Also, when comparing springs, "M" number (ie M90, M100, etc.) means meters per second. So an M90 spring should get you ~295 ft/s, M100 ~330 ft/s, and so on. An M100 is ideal for indoor use, M110 or M120s are good for outdoor use. Keeping in mind, I don't know what barrel length these spring ratings are measured at, with a long and/or tightbore barrel, you might shoot hotter than what I quoted.
