SFBs are great skis, but you might want to look into something a little more pow-oriented.... after all, the whole purpose of busting your tail skinning up the mountain is so you can ski deep pow on the way down.
That said... are you talking real backcountry, or exiting the gates at a resort into Slackcountry? Are you concerned about weight on the way up, or do you not care and want full alpine performance on the way down?
If you're looking to really get into it, get your Avy 1, etc and do longer tours then you'd be looking at getting a light ski like a DPS, Praxis, etc and mounting with Dynafits, Plums, and the like. If you are going this route, keep in mind you can't be skiing these consistently at the resort or you'll have issues with the bindings as they aren't meant to take the abuse/torque of in bounds bumps/crud.
I don't do extremely long tours (there aren't really that many in the Wasatch anyway) and want alpine performance when I'm going down, plus I ski my setup in bounds through junk snow pretty often, so I'm on Armada TSTs with Marker Dukes. Heavier setup, but can handle anything you throw at em.
And just as important as the skis... if you're leaving the gates, please get a good beacon/shovel/probe and take classes so you know how to use em. Lot of deaths in the BC these days, especially this season.
Pretty solid advice all around here. Colorado definitely has problems with their faceted snowpack. I just got my Avy 1 cert in Utah and that class completely changed the way I think when I'm in the backcountry... worth every penny I paid for it.
For your first touring setup I'd stick with something like a Baron/Duke... as others have mentioned going the Dynafit route is extremely expensive and requires a specific touring boot (which is also very expensive). Plus the versatility of Barons/Dukes means you can ski em in-bounds too.
I'm running Black Diamond Ascension skins and love em... zero issues thus far, just take care of them/let them dry at night. BCA Tracker Beacon is very simple to use (though they have a Tracker 2 out now which im sure is even better). Maybe getting too in depth here, but when you're getting your shovel go for one that has a relatively flat back to it so you can cut cleaner walls when you're digging pits.
I've never skied ON3Ps but they seem to get great reviews from everybody. I give my TSTs two thumbs up for touring- has the fat JJ tip rocker up front for float in pow, slims to 104 underfoot so you can carve if the terrain gets a little harder/icy, and no tail rocker means more grip going up steeper skin tracks. Don't know if you're looking to buy this winter or next, but next year 4FRNT introduces the HOJI which was designed with touring in mind- 114 underfoot (I think) and very light.
