Default PSI 1511 or PAC 1211x

Hey guys I posted this in another thread but didn't get much feedback. My cam specs are....

Eps 222/234
.604"/.604"
115+3

So it's kind of a sleep cam with a larger duration and lift. I want to run a beehive for the weight and valve control. I think I should be fine with either the pac or psi spring as they are both rated to .625 lift. The pac springs though are quite a bit cheaper so I was just seeing if anyone had a preference one way or another. I know pac makes a good spring but I just have never seen the 1211x used so I'm a little skeptical about trusting a motor with it

I've used both, PSI would be my choice $$ allowing.

I'd do the PAC 1519 with EPS lobes. 150lbs seat pressure will be your friend and so will a nitrided ovate wire.
