GPI on old vs new VAP arrows

[HUNT JR]

I currently shoot the older VAP 300 spine arrows that are no longer being made, and almost impossible to find anywhere. I want to move onto the newer ones that are available. My question is, does anyone know what the GPI would have been on the older VAP 300 so that I can compare and make sure I will be close?

Thanks in advance

Do you know which vap model you are currently shooting?
My tko v1s are 9.5gpi in 300 spine
Looks like the original vap may have been 8.7 gpi if this is the right one. https://www.victoryarchery.com/vap-hunting-arrow/
