The biggest advantage of Mejzlik CF props over APC is wider hub. This is important in a gasser with six small bolts. An APC hub is too small, so it can not be used on a gasser.

Mejzlik Cf props are generally as heavy as APC's. 16x11 3-blade is 126 g, about the same as 17x13 2-blade APC.
Haven't run one yet, so no experience. Also 17x10 3-blade narrow blade is interesting, 86 g.

More or less CF props are good for showing off, they look cool.
