I have Urushi, the tracking weight is somewhat in David's range. Sound is a little dull when weight is over 1.9 gram on my Graham Phatom tonearm. VTA varies with individual's music preference. My tonearm isn't completely parallel to the platter, the end of the tonearm slightly tilted at the end to get the highs for my taste. The angle of the cantilever really matters and should be the reference point. It also depends the type of vinyl you have, ie 120 gm, 150 gm, 180 gm or 200gm. Majority of my vinyl is between 150-180 gm.
