Do you know the spring pressures?

Thinking here...there has got be a reason why the Hyd rollers are not durable. P-Dude had a big hyd roller in 535 shifting at or above 7k rpm. He swore by hyd rollers.

Is it the brand? Is it the spring pressure? combo of both? KRE says on their website they have used Lunati Hyd Roller lifter with good success. What about an isky product?

I guess my thought is, if you are going to run a hybrid setup then why not just run a street solid roller and make a lot more power?
