Going with Aloris or PhaseII?

Phase-II works for me.

I've only seen one PII, but it looked well designed and worked fine.

Phase II uses a piston to push out on the Aloris style holder. Only
the angled surface and the psiton make contact.

the Aloris brand expands the Z taper with a wedge making full contact
on the entire Z area. WAY more rigid. May not make any difference on
light lathes with small cuts. Pour the coals to it with a heavy cut
and insert tooling; the difference is night and day.
