Drag Launch Springs

FRPP Cobra Jet springs vs. UPR Drag Launch springs?
Input? I read great reviews on both of them. There isn't a significant price difference.
Pros's? Con's? Experience with either setup? Any information would be appreciated.

Also, I'm not a 100% sure, but I believe Eibach makes both the CJ Springs and the UPR Drag Launch springs.

Yes, it is going to be a straight line car, no road racing. Little street use.

I'm running the 'non-lowering' CJ springs (M-5300-Q) and I'm satisfied with them. They dropped the rear maybe 1/2-3/4", essentially leveling out the car (measures 28.5" from floor to top of fender well arch at all four corners).

The fender-to-tire gap isn't too bad with my 17" M/T ET street bias ply tires (26.5" diameter), I'm less concerned with the slammed look - I want it to work at the track
