Speedy is correct in that the first indent closest to the point of rotation in 1 gram with each increment being 0.5 grams. A question. Do you have the silver base with your ZYX? From the sounds of your problem, I would guess no. Without it, you may be correct that no weight is optimal since the cartridge weight is very low - about 5 grams if I remember right. FYI. I'm using 1.5 grams with my 2.2 & Airy 3 combo.
As far as the blue damping fluid, I believe it was developed for the heavier bearing cap of the 2.2 and may not be the best choice for a 1.5 with a very light cartridge. Check wiht Bob Graham.
