Stay away from the 1.12 Reaction number
When you have 2 gear spreads use the one with the number the farthest away from 1.00.
I would look at the 2.16 -1.45 C-1 .73
If you can use just a little more starting line ratio the second gear drop will pull the car up to speed quicker. The 3 speed will get you in hi gear a little farther down the track with the 3 speed than the PG. It will also make your converter react like it is tighter.

2.16 1.45.1..... -32.9%..-31.0%....... 7200........4833.......7200........4966

I just guessed at the shift point.
Guess you have a 1.98 PG low..
The PG has a 49.5 % drop from low to high a 7200 RPM shift will bring the mechanical RPM back to 3636
See the difference in hang time on the converter. You are using second gear ratio to move the car instead of converter. I hope this helps
