Forge BPV spring selection for 25psi boost...

Please help me out on this.
I've blown my stock -110 type Bosch valve for the 2nd one. So here it's time to upgrade to the Forge valve.
My stage 5 boost is about 21psi but I could see 24-25psi at somepoint.
Question is there's a yellow one rating 15-23psi, then the Blue one 23-30psi, plus some shims that came with the box, what is the best combination for my application?
Since I boost up to 25psi would just throwing in the blue one do just fine?
How about using the yellow one and putting all those 2 shims? Would I still get enough "by-pass" for backpressure when having those shims on?
TIA Guys!
