Tonearms with no anti-skate adjustment

Anti-skate is very important. I would stay away from cheap tobearms which omit this feature. 

And what of expensive tonearms that omit anti-skate like the Schick. Are those better?

I owned a 714 and it worked best with low compliance cartridges, for me. The 704, 727 and 747 mated best with the F9e, etc. IMHO. So I did not see it anywhere; I was an owner. All of the repeated info on the effective mass of the arm seems to originate here:

The internet seems to merely echo unsubstantiated claims until they are no longer questioned.

But for a moment, let’s give that low effective mass number credence. I’m with Mr. Lederman. Your Shure V15 V , or other light tracking, high compliance cartridge, may not show signs of overt mistracking in an arm sans anti-skating, but the wear characteristic on the stylus will be uneven. I believe this also implies that groove wear will also be uneven as vinyl is softer than diamond. Audio is a thousand different religions. Pick yours.

That should say, ...707, 727 and 747...

Cleeds,
Stringreen has made no mistake.
Unipivots are generally designed to be as stable as that configuration permits. This means that ”lowering the tail end” increases downforce not decreases it as you have suggested.
