I can’t over tout the keyed dop sticks. They are fine and the default on the UT dops. Yes, the keyed transfer jig does really reduce the error. The UT V2 with the collet is one of the pre-keyed quill units. It is pretty expensive to change over to the keyed spindle ($1,250 USD). So, if you are OK with the collet, I’d just not get too concerned. If you pick a big enough facet to align with on the girdle, it doesn’t take long to adjust to line up the crown facets with the girdle.
