Primary options to go under my 62/71/13ss

[Spooler]

I have been thinking about going to compounds. I do tow heavy with the truck. What are the benefits and pitfalls of going S475, S476, or S478. Which one would work better for me? I have been thinking about the S478 with a 1.1 a/r.

where in the rpm are you needing more boost?

Upper RPM. 2100-2200 rpm up

I'd get the 78

I'd get the 78

That's what I am leaning toward with the 1.1 a/r. I would like to learn more about the design aspect of it. PR calculations, etc.
