My daily driver is a Capita Black Snowboard of Death 159. Mostly backseat camber with flat/rocker zones out past the bindings. A little bit of taper and setback for powder. Great for all mountain charging and freestyle, and can still dart into the trees and have a lot of fun hitting pow stashes, then zip back out onto a groomer and rip it up. That's my favorite kind of riding and after trying a lot of different things I found I prefer camber dominant boards.
I have a Niche Aether 156 for park/mellow hungover days. Those boards are both mid-wide, I like to stay in the 254-259 range for waist width but like I said that's a personal preference thing. I also have a Capita Charlie Slasher 161 for powzer days.
I really like my quiver right now. The only thing I might consider tweaking is something with the shape/profile of the BSOD but stiffer. Capita Supermacho or Mercury, Yes Pick Your Line, Ride High Life or Berserker.
I live in California. When I lived in LA I went to Mammoth a lot. Now that I'm in SF it's mostly Tahoe. Mammoth is an incredible mountain. Some of my all time best riding has been in the natural terrain on the backside of Mammoth and the slackcountry there. Tahoe is my favorite place on earth. Absolutely gorgeous, awesome terrain, and you can't beat having a dozen resorts all in one place. You can go there for a week and ride a new resort every day if you want. Favorite Tahoe resort is Sierra. 90% of the terrain quality of a place like Squaw or Heavenly with a much more chill, laid back local vibe.
Lib/Gnu make awesome stuff. I've owned several of their boards over the years and really dig them. C2 and it's derivatives are an awesome shape (my Niche is a C2 shape) and the boards construction is bulletproof. They just flat out know how to make a badass snowboard that's going to be fun to ride, regardless of the exact shape or what it's designed for.
