Recommended Recoil Spring Weight for 5 In-Line ports?

Hi all,

Does anyone have 5 in-line ports on the 43x (from Fourged Group)?
I’m debating if I should get the 15 lbs (ISMI brand) spring or 13 lbs spring (Centennial brand).

The question applies to 4 in-line ports too, I’m considering between the two options.

Thanks in advance!
