RE: You've only given us half the relevant data, unless...

I think it is far more important to have the tip (azimuth) perpendicular to the groove (particular for Line Contact types with a large bearing radius). For an elliptical tip (made with front and back face cuts), this is important since the contact patch is pear shaped. A tip azimuth error will result in a different effective scanning radius on each wall. It is even more critical for a Shibata since the effective SRA is defined by the cut and the curving contact line will result in a differing effective SRA on each wall.

Aligning for tip azimuth may or may not correspond to the body being normal to the surface since cantilever rotation (and skew with MC) is incredibly common and the mounting tolerances for the tip itself are of the order of 1 degree (Expert stylus) for SRA and/or tip azimuth. Shure allow up to 3 degrees (I recall reading somewhere) and a recently purchased Ortofon 2M Blue would suggest that Ortofon allow up to at least 2 degrees error.
In my experience, aligning the tip itself results in a significantly cleaner presentation and improved imaging even if the channel balance is off for the lateral signal.
