My fav spring too for singles. Very light and seem to last like OEM. I bought a large lot of sets from a NASCAR team with only testing time on them and I hoard them like jewels.

Tech @ WS6, no worries. Cam envy is a real thing(me included) and for a lot of folks(nobody specific), you are absolutely right; they'll want the other "bigger" cam.

I wouldn't do the GM springs on a project vehicle, but I would consider on something I am going to put a lot of miles on potentially hauling people, etc. The GM factory springs leave a lot to be desired but we've all seen them go 150K-300K depending on the engine.

Is there data like that out there on the popular single and (especially)dual setups? I haven't put but 10K miles at most on any of my duals personally and planned to check them real closely if I ever got to 25-30K+. Then again, my work schedule, 30K will take a very long time at my current rate.

The real hayday of the beehives was 2009-2011. So many bought they sold like water. Im pretty sure there are a ton of builds out with beehives, but most dont think to check em.
Tsp does offer them as an option with cam kits and on heads if that gives you any indication.
But no long term tests ive seen.
