This list is all over the place; can't get much more different than a Cochise and a Rocker2 108. How did you arrive at it? FWIW, "light and playful feel" or "light and easy" is not how I'd describe several of these skis, let alone a Bonafide. Especially if you found a Crimson Ti to be too powerful or sluggish and go out of your way to ding metal skis.
Instead of trying to convince you to get a narrower beefier ski, I'll stick with your own adjectives. Especially at 178 lbs. Especially as an ex racer; you know your own head and your own mission. Especially since you have the skill set to actually enjoy a lighter more playful ski in a variety of conditions.
I'd keep the Rocker2 108 and the Peacemaker on your list, toss the rest, add in the Head Collective 105, Fischer Big Stix 110, Sir Francis Bacon. If you wanted to go fatter, then Patrons. Go forth and have fun.
All over the place is right. I read a lot of reviews on Blister and other sites, and spoke to a few friends and shop guys who've skied some of them to get started building my short list. Without having access to demo days anymore (used to work in the industry years ago), I'm always behind now on what the new crop skis like. Demo'ing is the best for sure, but I also don't get out as many days as I'd like, and not all of the skis I'd like to try are available, so I'm trying to make a short list of highly-regarded skis from skiers that I can identify with, and then focus in further on what might match me best in this thread here. Then, I'll either demo the final 2 or 3 that seem to make the most sense, or I might just wing with one of the finalists.
