Male 31 years old, skied since I was 12, raced in jr high and high school; skied 4 days a week in high school. 5'-10" 175 lbs.
Now that the basics are out of the way, the long winded stuff.

I taught my wife(girlfriend at the time) to ski about 7 years ago. Shortly after, we bought a house, got married...and just kinda got out of it. Fast forward to this year. We went up to Stratton, VT for two days, had a great time, 3 weeks later she has a Pair of K2 Sweet Luvs and Salomon Devine 10 heated boots.

Since then, we've made about 3 trips to Mt Snow. My wife is HOOKED and loves skiing as much as I do. It's awesome.
I'm currently skiing on a set of 188cm K2 El Caminos.....circa 1998(?). From what I recall at the ski shop I was working at at the time, these were basically the K2 Four, minus the piezoelectric (sp?) damper. Bindings are Salomon 997 Carbons. I really like the ski, but feel it's time to upgrade given how much things have changed in the last 10 or so years.
We live in CT, so we usually ski up in Vermont. As you know, conditions can vary. Since my wife is still somewhat new, we've been sticking to mostly blue cruisers. However, I do like to venture into the terrain park, trees, and really open up and crank out some nice GS turns. I don't know how to describe my style. I sometimes keep both skis on the snow, but for the majority of the time, I lift my inside ski up a bit...guess that's an old race habbit.
So, I'm looking for advice as to: What skis to look at and: What size to get.
The Head Monster78 keeps popping up. I was at a local shop that had a pair, but only in 165. I was thinking that would be a bit short. I know I'll drop down from the 188's currently, but thought 165 was a bit too much of a drop.
I'm open to pretty much any brand, so let the suggestions fly!
If you need more info, I'll gladly post it.
Thanks in advance, I look forward to the responses!
