Heavy duty vs Regular Duty

I just don't know which spring will be best.

These two springs are out of a 4L60E Superior Shift Reprogramming Kit. (see pictures)

Heavy Duty and Regular Duty is all the info I have.

Can anyone give me some comparison in shift characteristics in the two?

98 Chevy K1500
5.7 350

It's no hot rod but I would like it to tow occasionally.

Has anyone used one of these in a similar set up?
