mechanical complexity can also be compromise. the more adjustments involved, the higher the material quality and precision requirements for the same level of performance. no free lunches.
some of my earlier arms did have VTA adjustment on the fly including some mentioned. my current arms are better performing (i prefer them) but can’t do that. the exception was my Rockport Sirius III linear tracker; but it’s build quality was off the charts.
bearing towers need to be rock solid.
the point i’m making is that beware of buying features without considering the whole picture. is VTA important? yes critical. what is the net performance result of on-the-fly VTA adjustment capability on a particular arm? does it exact a cost?
i suppose it comes down to your expectations for arm performance.
