Basically that's what I've done, not that I'm an expert or anything but it seems reasonable. I added several extra weights to the long rod, and extra weight to the side rod on the opposite side to the sight and plunger, which allowed the bow to balance straight when held as above, rather than have a tendency to yaw over to one side.My quick and dirty approach:
Place a finger on the back of the bow opposite the grip, long rod hanging down: it should balance level with or below your normal pressure point on the grip.
Then turn the bow upside down and place a finger underneath the extension or long rod. It should balance an inch or so forward of the stabiliser bushing.
So the centre of mass is slightly forward and slightly down...
I bet if you check you'll find the balance is a bit forward and slightly downI tend to set up my stabilisers by feel, as you can follow the books and other peoples recommendations All day but it may still feel wrong to you.
I just added and removed weights/ different extender lengths until i liked the feel of the balance, and found the balance between to heavy and to light etc it?s very much trial and error.
It may well be if I was to check it, but not as far forward as some as I don?t like a sudden fast dip, I prefer it to dip a second or so after the shot and allow the lower limb to stop on my leg.I bet if you check you'll find the balance is a bit forward and slightly down
