front bag size??

[MMM...BRAINS...]

Ok, quick run down:
Ive got a '50 1/2 ton goin on a '91 s10 frame basic SBC 350/700R4.
(This will be a daily driver that sees quite a bit of miles.)
My questions is about the right bags for the front.
I definatley want to run Slam Specialties, but the question is what size??

RE6 or RE7???

Ive read alot over on the s10 forum and they all claim the RE7 ride better/smoother do to lower PSI at ride height. that i understand. you also have to do more trimming out the spring pocket to fit the 7s.
and while i do want a GOOD smooth ride i don't want it TOO soft. (I WILL be running shocks and sway bar up front too)

so i guess my main question is to anyone with experiance in this area, is a RE7going to ride smooth but NOT like an old caddy? or should i go with the RE6 and let it be a bit more stiff.

Thanks,
Chris
