there so sick, fun ski as hell! very light, poppy, and stable. Fairly stiff, softer in the tails...I reccomend them!

i have heard that they are very stiff

stick with a more buttery ski
aka-ar6, thall, fujatives,  or invaders

How do you know he doesn't want a stiffer park ski man, why should he stick with your suggestions when you don't even know his body setup, age and stuff and his riding style, what he prefers in a ski and so on...
Please don't recommend shit without knowing shit.

To the thread creator, obviously you just want to know what the ski is like but a little more information could be helpful. 
The ski is sick man, real light and poppy, and as above it is fairly stiff but not like the karma was.  It has a softer tail than tip which is a little more foregiving and helps with the pop.
They are a killer jump ski that holds its own on rails.
They did have a few problems with edge weakness and shitty topsheets a few years ago, but they are really solid nowadays.

Ive heard they have had durability problems...but they may have improved on that now

That is all sorted now, it was mainly in the first generation skis, and then in the 3rg G (i think) they made them in Africa or somewhere and had uge problems with edges and other durable issues.

AR6s are not buttery.. they are poppy. theyre different.

here's like two sentences of information on them...

Where the hell are you hearing they are stiff people? theyre not at all, i ride them and im 5'11 and riding the 177's and i want the 183's cuz i slip out way too much. but theyre super fun. the tnk's are stiffer and better for bigger jumps but the stls are super light and fast on rails and have an awsome carving ability. go big when you order though for the stl's. way buttery.
