I would think you can figure it out just by distance gain/loss. Like mentioned above, my SS went down a few mph with the KBS' (120 g) compared to the GS 95 (90 g) but my distance actually went us since I was hitting it on the screws. I guess you just try heavier and heavier until you notice a loss of distance. Sort of like playing a shorter driver shaft.
