Replying to Icelantic keeper vs nomad

So I've been scoping these two skis out quite a bit but I've hit some crossroads and need a bit of advice/opinions. I've been riding 07 Seth vicious' for quite some time now and have loved them but I've finally beaten them to death so it's time for some new rides. I'm an aggressive skier, spend most of my time in crud, trees, and bumps but I also do a small bit of park, and ski quite a bit switch. Also, when all else fails I do enjoy some carving at high speeds down steeps and/or groomers (way back in the day I was in a racing program so sometimes that sneaks out of me). I'm 6'2" and a fluctuating 180#. So here comes my dilemma. I currently live in Maine and have been shredding Sugarloaf my whole life, but I am moving to Colorado next year so that has put me onto micro skis and such. Since I won't be west coast til next fall but need to pick up the skis soon/this season I won't be able to demo these guys. Since my Seth's are pre-rocker I'm fairly ignorant to how early rise skis feel on harder pack conditions. So basically my questions come down to these quick points: 1) which ski would I prefer in the bumps/trees since I would stick to the 180ish length. Would the keepers be too sluggish? 2) if I went with the nomads (which I am leaning towards), would I really regret not picking up an everyday ski with no early rise tip? 3) how do these models perform at higher speeds in bowls, chutes, etc? Important side note: I will be picking up some playful über rockered skis (probably hellbents) within a year as well so the skis I'm picking up now will act as an average conditions ski with a lot of days and potential groomer days. They would probably travel with me home to the east as well, however this isn't too much of a concern for me.
