the blend is gonna be a great all around ski, it kills it in the park just as well as any park ski, maybe a tad heavy for tech rail stuff but who does that stuff anyways. the kung fujas is literally a softer blend, not much softer, id say the blend has a stiff flex and the kung fujas has a medium or maybe medium stiff flex. but other than the flex there isnt much difference at all, the fujas is a tiny bit narrower, but the 179 is a tad longer than the 180 whatever blend so it floats just as well.
the lizzy is an awesome ski and its pretty damn good in pow, its a little short for powder, but if you mount at reccomended which is just a tad bit behind true center it will do great. and its fun as hell for park, its really does feel like a snowboard and its light.
the closest thing to a lizzy i can think of is a live life 2 which is longer and maybe a little better for pow, but alot stiffer so its much better for huge jumps.
if it were me it would either be the fujas or the lizzy, cause i like a little more buttery ski, and the width gives it more than enough stability for big jumps.
