Spool vs SG

I run a spool in my street car and use a standard street (non-drag)radial. I have had zero problems with axles or my Green bearings. The car turns great although I am not trying to roadrace the thing either. I build custom rearends for a living and I realize the drawbacks of a spool on the street, so i thought I would give it a try. Well its about ten years old now and no breakage and it actually drives very good, even in the rain. So bottom line is run the spool especially in Arizona.
