I was specifically advised against the RST because it's not intended for use with sticky tires. The RXT was recommended instead.

I'm going to inquire about a Soft-lok clutch tomorrow. With the drag radials, my power and weight, there has to be a "weak link" in the system somewhere or it's going to break parts. Since you can't "slip" a drag radial tire like you can a bias slick to absorb some of the initial hit, it has to be absorbed by the clutch. In my case, it <span style="font-style: italic">has to</span> slip a little bit on the initial hit, but lock up once the vehicle is in motion.
Here's a good read on the Soft-Lok over on the Chevelle site:
