Hello Ct0517 & Dover, of course no offense taken. The discussions about the significance of variations in horizontal mass have been of interest here and in several AA and DIY forum threads. I have yet to try a really low-compliance cartridge on Trans-Fi-- which may change my current opinion that "less is more" w/r to horizontal mass. I've experienced this with a large number-high compliance MM/MI cartridges and a small samples of medium-compliance MCs.
I'd have to dig for the URL, but I recall that either Mark Kelly or Poul Ladergaard calculated the lateral stylus force applied by a linear tonearm as compared to force attributable to overhang and off-set in a conventional pivot arm. If as modeled, the lateral forces of a pivot arm(to which we must also add the tonearm's effective mass) are significantly greater than that of a 100gm linear arm, then this may suggest that a linear arm(whether 35gm or 100gm) cannot be faulted for its large lateral mass. Perhaps this is what F. Kuzma meant when he said that 100gm is "no big deal." In any case, I was not suggesting the relative superiority of any of the three very different linear arms under consideration.
