Question on VTF (What should i adjust it to?)

@kro77 , I just got a new Voice but won't have a turntable for another month or so. Do let me know what you think of it. The Voice is a moving iron cartridge. The iron wiggles between the magnet and the coil changing the magnetic flux. The Iron weights much less than magnets or even a coil reducing the effective mass of the moving assembly of the cartridge which should improve tracking. 

@noromance , The Decca is not a cartridge. It is a chisel. Don't expect it to act like a normal cartridge.

@lewm , no doubt. There are many biases; visual, expectation, cerebral etc. They do seem to be predictable. Tweaks always seem to make things sound better, hardly ever worse. I think individuals think they can filter their own biases, "I am in control." This is an illusion. Every time I test someone's reflexes they laugh. There is this quick realization that they can't control it. The leg is going to jerk regardless of how hard they try to stop it. There is a lot we do not have control over, our central nervous system is a prime example. In control? Under the right stress your brain can make you kill yourself. It can make a woman kill her children. It can make you steal a Mustang GT500 and speed yourself halfway across the country before managing to get arrested (True story! This was a manic Budweiser executive who stopped his meds. He erroneously though he was in control.) You are not in control, you are just along for the ride. 
Now I'm going to get that male ego, ruffled fur business and how FOS I am.  I admit it ahead of time, I am FOS. Should I report myself?

Kro means the cartridge has a range of 0.3 grams. It is not the overall tracking force.
Lewm's suggestion is the right one. It is all a matter of tracking.
