Fact - When you install the new c/w and disable the VTF spring you will have to adjust VTF by measuring it with a scale. (This is good.)

Fact - For the scale to work accurately you must zero out AS.

Conclusion - You will have to reset AS afterwards.

Recommendation - The AS device on Rega arms is notoriously inaccurate. Most people find the optimum value to be lower than the scale indicates. Nsgarch's world-famous visual AS-setting method is easy, effective and free. (I'll let him type it - again!)
Jea48,

With all respect, you are confusing things.

Why do you want to disconnect the antiskating?
He never said he wanted to disconnect it. He asked if he should "touch" it, i.e., readjust for any reason.

Where ever you had it set before the Heavyweight just leave it there.
Changing the c/w, disabling the VTF spring and setting downforce with a scale REQUIRES that antiskate be temporarily disabled, as I mentioned above. Further, the use of a different c/w and a new VTF can alter skating force. He may well need a different antiskate setting.

I believe some VPI arms do not have any antiskate control.
That is not true. All VPI arms have some provision for antiskate control.

The simple procedure I mentioned above should produce better results than just leaving AS wherever it was before. There is no reason to assume that his previous setting, which may or may not have been optimal, will also be optimal under new conditions.
