A518/46RH transgo TFOD-HD2 shift kit install

Another question about the transgo kit.

I'm getting ready to drill out the 1-2 and 2-3 holes in the separator plate.

What size should I go on the holes? Use the largest in the range they give? Or go middle of the road.
Their specs are divided into Towing/HD, and Street toys. So I assume I fall into the Street toys category. So for the 1-2 hole they give a range of .093 to .106
And for the 2-3 holes the range is .125 to .135
Bigger hole = firmer shift.
So my question, go big or go home? Or go middle of the range somewhere?

What did you do?
