appreciate any feedback that u guys r using...cos mr wong fr top perfect recommended me 8kg front and 3-4kg rear..the rear sounds reasonable to me but the 8kg front sound HARD!! according to him, the springs are progressive so i can still get comfort at low speeds while at higher speed, it will be stiffer...but 8kg seems TOO stiff for me...mebe the damping rate is softer to match the hard spring rates?? kinda blur here..

wats the difference between the linear and progressive springs...
