Replying to Not another fat rockered ski thread

Actually it is. Sorry for the deceiving title. but really i do need help. I've looked at reviews, search barred enough to fry my brain, and talked to everyone i can. But, I still can't decide. I've got a couple of skis that I'm interested in. I've got spk skis for park days and i have rossi scratch bcs, but i want to sell those and get a fatter, rockered ski.
First of all, i should tell you about myself. I am 5' 10" and about 140. I'm a aggressive enough skier, but I don't really charge a whole bunch. I want to get a longish ski and center mount, or close to center mount it. Here the skis im kinda looking at.
The moment bibby pro. its length is 186 and here are the dimensions 143-115-134.
K2 Hellbent. probably 179 and its 150-122-141
volkl chopstick 185 and its 148-128-148 (more hesitant because of bad reviews)
faction royale 183 and its 150-120-140 (i think thats the dimensions for it, found them on a poster)
salomon czar 182 and its 128-108-118 (hesistant also due to only front rocker)
line sir francis bacon at 182 and its dimensions are 142-115-139
i know thats a lot of stuff to think about, but i truly want to spend my money on something that is worth while and that i will like. thanks a ton, and i'll give karma to anyone who contributes (positively haha)
