dynamic golf S300 shafts - how stiff are these?

In terms of frequency, PX 5.5 comes out a tiny bit firmer, at Rifle 6.0 versus TTDG S300 5.8, but frequency doesn't tell the whole story.

Playing characteristics are different with PX being firmer in the butt so feeling harsh to people who are not hard hitters, but softer in the tip for a medium launch. TTDG have a bit more feel but are tip stiff. They also tend to spin more for some players.
