alright so fujatives came out a few seasons before silencers... so they were THE k2 park ski, while the public enemy was a heavier all mountian twin tip ski with the dimensions 113/80/104... after the first season, the public enemy dimensions were beefed up another 5mm all around to keep the same sidecut and turning radius. now they were 118/85/109 and pretty heavy for park skiing. a few seasons later, k2 realized that people like the sidecut and radius of this ski but wanted something lighter. this made the arrival as the k2 silencer, 113/80/104, a softer, more park oriented sibling to the public enemy at a lower price than the p.e.
if you have tested the fujative, silencer, and public enemy you would notice the difference in turn radius, flex, and weight.
the fujative is a noodle and has very little sidecut, thus making it mainly good for just straight lines toward a jump or rail in the park and not very good for just all around carving on the mountain... unless you have a decent amount of skill actually skiing. 90% park 10% all mountain (the k2 site said it a while back)
the silencer is a light, all mountain one ski quiver for somone that can only afford one pair or whatever. this ski has good pop in the park and has a decent waist to stomp the big tricks, while also having the sidecut of a more all mountain ski, enabling it to be able to get on edge easier and quicker. 60% park 40% allmountain (k2 site)
the public enemy is a "heavy" all mountain ski that is also a twin tip model.. decently wide waist for a little powder but not really a bc ski, just meant for ripping all over the mountain with the added stability of an 85mm waist for high speeds.... 20 or 30% park 80 or 70% allmountain
and the fujatives were designed when pep was more into the park anyway... and he does use them when he is in the park other than when he was on the hellbents
hope i dont have a bunch of info wrong here, i used to be looking for a k2 twintip as my first twintips and did a lot of research on public enemies and silencers a couple seasons ago... and my brother and my friend both have the 06 fujatives and i have tried them out
