When is a T-6 better than a T-4 for large single?

Trying to find some info on the use of a T-6 turbine vs a T-4.. When is bigger better?

When you run into drive pressure issues with a T4.

How much fuel and RPM are you throwing at the turbo? What size turbo? Goals?

Its an 80mm/4k ish 03 CR w/UDC
, i was just curious if or when a T-6 would benefit. I'm not exactly sure of my drive as my gauge is on its way out, been fluttering like an old chevy speedo.

Is there any spooling difference between t4 and t6? Assuming you bought manifolds not the adapter. I have a 472 with a .90 t6 on it didn't know if a guy should go t4 for DD.
