The stabs look almost identical; the only thing we've changed is the twist in the profile, from the root chord to the tips.Although this might sound insignificant, our team actually found that this small tweak improved just about every aspect of the P stabs.Better pitch control, more manoeuvrability and improved pumping.The PX sizes come in a slightly smaller surface area than the P.PX160 replaces P165PX175 replaces P180PX195 replaces P200Expect a little less front foot pressure when changing from the P to the slightly smaller PX. The PX pairs perfectly with our new Carve 3.0 range but can also be used with any of our other front wings: Glide, Glide 2.0, Carve, Whizz, specially if you want to improve the general performance of your foil for high speed winging and kitefoiling or when you are tackling bigger and faster waves.
