I think you have a misconception about the importance of overhang. If you take a 9-inch tonearm aligned for null-points of 66-mm and 121-mm, and you increase overhang by just one-millimeter while keeping linear offset and mounting distance the same, the new null points will change by 10-mm each. Furthermore, the null-points will now be 20-mm closer together yielding significant inner and outer groove distortion. This is from sliding the cartridge forward only 1-mm in the headshell with all other adjustments remaining the same.The difference between Löfgren A and Löfgren B is only 0.5-mm overhang. That's right; both alignments have the same exact linear offset and mounting distance, but Löfgren B has 0.5-mm longer overhang and this moves the null-points from 66-mm and 120.9 mm to 70.3-mm and 116.6-mm. Overhang is very critical.
Good luck,
