How did this combo work out for you?

I've been running stock multileafs in my Nova. I installed slide-a-links with the solid front bushings years ago and was very happy with the added traction. Now I'm ready to lower the car with the same Hotchkis 1.5" springs. I face the same decision: keep or sell off the SALs and if I keep them, can I run the rubber instead of solid front bushings.
