Anti-Skate Grace T/A no weight now???

Since putting the Benz Ace on the Grace

(Linn LP12/Grace 707)

I have not had the antiskate adjusted quite right.

Now, I finally have it spot-on.

The only issue is, there is no longer a weight or even a weight shaft on the tonearm. They had to be removed in order to get the arm neutral.

Any of you run into this? I don't think it should be an issue, but removing the shaft and weight seems...extreme.
I ran this combination for a while and removed the anti skate mechanism entirely [ In fact I can no longer find it]. When I changed to a Graham 2.2 I left it off that also. I have found fooling around with AS is more trouble than it is worth; YMMV.
