What torqueflight 727 transmission rebuild kit do I need????

These look good but I read that if I replace my sprag I would be best off spending double on a 16 roller sprag. Is this true or can I really use that 12 roller?

I have three 727 that use the 12 roller I have never needed the 16. But at the most I'm only running 450 horsepower.

Two of them are in four wheel drive full time Transmissions.
