The problem is not to "walk the line" the problem is walk the line without interfering with the other arm's
Styrk - Sounds like you are setting up for a tonearm "party"
:^0
You know - Years ago I tried different TT's with multiple tonearms on them. On three occasions. These were two full plinths and one setup using armpods. The party/experiments for me failed because I would only end up playing the ET2 after some comparisons. To those interested, I could only get the other tonearms to sound like the ET2 on two parts of the record; you know what I mean ..... when the presentation is really in focus, on those two points when a pivot arm alignment hits the sweet spot on a record. Hearing this phenomena using familiar LP's with these other tonearms, was interesting, in an audiophile way, but also the end of the road for them. Just saying. ¯\_(ツ)_/¯
In my record collection I do have many mono records - have found over 100 so far and counting , so the plan would be to put my second ET2 on the La Platine in a custom install someday, to listen to these records with a mono cart.

It's a straight, but lonely road.
