Best K-Frame for improved handling?

Hey autoxcuda, is there any preference in k-members between the 72 style or 73? Right before I moved to Vegas I was putting the front end together on my 72 duster. I put in .990 torsions, reinforced the lower control arms, poly bushings with new lower pins, and larger strut rods. I saw the strut rod bushing mods on Mathew Grubels site, but didn't have to cut that much since the new strut rods were about 3/8" shorter.

Sorry, I started rambling:stop: Just wanted to know if one was preferred over the other since the car is far from complete and the k-member could be changed without too much trouble.
