Best way to find out is try it out. Trial and error is the only way you'll really find out because every marker is different.

^QFT, I used the light spring when I went to LP because I have a titanium hammer so I needed to get a better dwell time. (less weight/mass inertia striking the valve pin)

Well, you should try all the spring combos, weird things happen, sometimes the stiff valve spring works best.

you only need a lighter spring if you get a lighter striker. otherwise your fps will shoot up to about 350.
