A pretty fair description imo.
What set up are you going to settle on?

FP springs, FP nickel plated needle jets, FP needles.

I actually like the DJ needles a little better, only a hair better, visually and functionality [when used with the fp springs]. but after only 500 miles [combined with new FP nickel plated needle jets] the DJ needles actually showed signs of wearing!! EEK! enough so that I knew the profile wouldnt mean squat after long. so the FP needles went in. the difference in performance IMO between the FP and DJ needles was very very difficult to tell, but ever so slightly noticeable. both were way better than stock though. and I now have 2500 miles on the FP needles, 3k on the FP nickel plated needle jets, and zero signs of wear on anything, so I'm very happy

from my calculations, the original springs are 92N/m, factory pro 29, dynojet 21 and original 400ss/m springs 37.  the lengths follow that sequence too, from shortest to longest: original, dj, fp, 400.

compressed to 70mm, the original have 2 N load, the dj 0.5, the fp 1 and the 400 2.  with the slides fully open (another 35mm compression) it's 5.5, 1.5, 2 and 3.5
