Not to harsh your excitement, but I've been where you're at: drooling over all the endless options of new skis.
Honestly, after 2 seasons of buying, selling (not to mention 3 seasons of demoing), I ended up with a rotating quiver of 5 skis.
I carted all 5 around with me all season, which is at 60 days and counting and included riding in Colo, Utah, Wyoming, Tahoe, and New Mexico.
Seriously, over the course of those 60 days I ended up grabbing the same 2 pairs of skis over and over again: Lib Tech Freeride (93/99mm waist thanks to Magnetraction) and Spatula (125 waist).
I've come to the conclusion that you really don't need more than 2 skis in your quiver: a 90ish waisted ski (closer to 100 being more optimal) and then a 125+ preferably reverse camber super-fatty.
Of course this depends on where you ride for the most part, but for the places I frequent (Cali, Utah, Colo, Wyoming, NM) this 2-ski quiver was optimal.
Additionally, I've found that a great deal of my friends have trimmed their quivers down. I ride with a lot of folks who have a pair of Bros (99mm) and then something like the Praxis or DP or ComiKaze (all +125 in the waist).
Again, I've been where you're at, drooling over the various options out there and demoing and making lists and I even went so far as to go through 2 different 5 quiver set-ups before realizing that less is more.
Plus with the airlines now charging for that first set of skis and gas prices being what they are, traveling with a quiver is becoming more of a hassle.
