408 hyd roller, too much spring pressure?

All Springs run best when ran close to coil bind
Correct. But not everyone does it.

And no-one is butt hurt about anything. At least not me. I use what I use but I'm happy to use something else if it's better and within my budget.

On that note, I would love to see your source for the claim that "beehives used in mass produced automobiles...the beehives have a very high breakage rate compared to the standard".

What is "standard" in your opinion, and what % of failures are there compared to beehives?

As Bewy mentioned earlier, there was a bad batch of Comp 918 springs when they stopped buying them from Pac, but apart from that, I would like to see real evidence. People (like me) reading this thread should at least be able to make their decisions based on facts instead of conjecture.
