Anyone swap to a softer Torsion bar?

I found the Spring rates for the torsion bars. I have an 4X4 Edge super cab which has the stiffest springs. I want a little softer ride and do not haul heavy stuff, nor are there any heavy accessories up front and I removed weight. I also already lowered the rear spring rate by cutting down the leaves, it rides much better. I am thinking of getting some of the 215lbers. Does anyone know what spring code, stamped into the end of the bar, matches the ratings below? I got a clue, the T-bars I want are in a standard cab.

Rating at the ground is 2510, 2710 or 2900lbs
Diameter 1.03, 1.06, or 1.09"
Deflection rate in pounds per inch 200, 215, and 235lbs
Spring codes
200 -
215 - "B" code
235 - 1 or A

I'd like to but can't afford a coil-over swap now and am driving a bunch.

I swapped out my "B" codes (1.06") for "A" codes (1.09") bars.

Thx. Looks like I will try "B" code springs.

I think it will ride better and still hold the truck up!
