F8 wedges vs

I hit the F8 irons yesterday and walked away wanting them and the woods lol.
I liked the GW and got thinking what's the real difference, significant difference, between the set SW and LW vs a King 54 & 58.
I'm not a spinner but a higher flight guy. So it got me thinking, why not do the set SW & LW over the Kings.
Has anyone actually tested the set wedges against the regular wedges?

Havn't done a direct compare but I did have the F7 55 degree wedge in my set. I think the advantage of the Kings is more swingweight and a different grind. Never felt comfortable hitting out of sand with my F7 because it was such a light club.
