Its often recommended not to use a PDI spring as they are old technology, the non-linear springs made by prometheus, systema, hurricane, etc. are all much better. When I had a gun with a Prometheus M110 it shot 368-370fps, my P90 with a PDI 170% shoots 390-401fps, a much larger variance. The spring I prefer and the one most recommended by many gun doctors and experienced games as far as I know is a Prometheus M110 or M120, the M120 will bring your gun over the 400fps limit on most fields if there are other upgrade in it (tightbore, piston head, bearing spring guide, etc.) so its usually safe to stick with an M110.
I am in no way claiming any exceptional experience, this is just drawn from my limited experience and what several heavily experienced members of these boards have told me, as always Illusion is the one to talk to for details as his wealth of knowledge scares me at times :neutral:
