AAARRRGGG!!! I'm still torn between BB and SB springs!!

I had started a thread in the Suspension Tech section
(click here) to address my spring dilema, and I was getting closer to choosing the BB Hotchkis springs, but now I'm not so sure. I, too, got rid of the A/C, will be running an RPM intake, am considering moving the battery to the trunk and I'm converting from my TH350 to a Tremec TKO II 5spd (which should be lighter). I know I can cut down the BB springs if necessary, but I'd really like to get the height and stance right the first time and avoid tearing the whole thing apart again, if possible.
