I have a pair of 4.3 and 2 pairs of Vapor 9s. Vapors for me give my the perfect blend of support and traction on both clay and HC. The lightness with the Vapors feels great and there's enough traction for HC but enough give to allow me to slide on HC.
I now seldom use the 4.3, they are comfy and have brilliant grip and stability but I've grown to dislike the short tongue and so much prefer the dynamic lacing and fit on the Vapors.
If you want a shoe with stability and comfort, I would also recommend B7s.
