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.

I've haven't made any 0.100" cuts in all my days, so far, but I see
what you mean. Have you experienced chattering or deflection problems
with a Phase II?

You're just a light weight Larry. You should be fine with a Phase II.

Deflection is a fact of life. making it rigid will reduce not
eliminate it. HSS really shines here, the cutting forces are so much
lower. Any time I have a part more than 4 L/D, I use HSS to finish if
at all possible. Or program in the taper on the CHNC lathe.

As to chatter i have a very old LeBlond where chatter is its middle
name. I'd get rid of it but its hard to find another ten foot lathe
for cheap.
