I just got started backcountry skiing this spring, and with the sierra snowpack its an awesome time to get out there. I purchased this pack and have skied one day resort with it, and two days backcountry so far. It is awesome!! Like one other review said, it definitely seems large at first ( Im 6'1" and got the lrg 32L pack) But once its on your back it doesn't hold you back at all. I have not yet tried the diagonal carry, but seeing how well the horizontal carry worked i would imagine it works just as well. The 32L is perfect for backcountry use and can hold perfectly all your avy gear, first aid, food, and extra layers. If you are just looking for a inbounds use pack, I would go with the 22L. All in all this is the most comfortable and useful pack I've used. (And if you don't want to be cheap like me, go with the AVALUNG built into it, Which makes for an even higher tech great pack)
I am on a hammerhead binding right now and I ski in position 5. Which power tube would fit that? could i get by with the medium power tube?
If you're looking for a true touring boot, this is definitely your best choice of boots. However if you are looking to do more hard charging telein I would go up to the Scarpa T1 for more support and stability.
