Transgo HD2 Shift Firmness?

[Hivelocit]

Instaling the Transgo HD2 (4l80e) and was wondering what hole sizes to go with for the ABC holes. Options are:

A-4th
B-3rd
C-2nd

Hole Sizes
Average= 0.86
Softer= 0.76
Firm= 0.96

I am going to be running a Circle D Triple Disc Convertor with about 2800 stall and turbo. Want to make sure I am not on the harsh shifting side by opening them up too far. I am assuming the 1st to 2nd is the one I should be more worried about? Any Suggestions are welcomed because everything I have read is a little confusing as there is not a definitive write-up given my mods.

Also which ACCUM SPRING setup did everyone use for shift firmness?

Both Large and Small springs (Average).
Large outer spring only (Firm).
Small inner spring (Firmest).

Thank you!
