Tube Bending Die CLR?

[Coarsegold1]

I'm getting ready to purchase the RMD 150 and plan to buy three sets of dies:

1.25" for Jeep tube fenders, body armor, etc...

1.75" for Cage, Suspension, etc...

2.5" primarily for exhaust tube work

What size CLR would you recomend for each of the three sizes?

Thanks in advance!

figure out how thin of tubing you'll be bending and get the tightest radius that wont kink it
