If you are going for a 1 set up quiver then sure do it, but if not then just get pins for a true AT set up. The shifts tour horribly. Theres no flat touring option, the toe lockout sucks, the riser options suck, have to pop out to rip skins and flip switches on the binding. Toured my pair for 2 years and will not be touring them or buying another pair ever again. Kick turns absolutely suck on them and because your toe sits so high up from the ski when you are touring it feels like you walk on your tip toes when touring anything above 20 degrees. Also they suck to deal with when its cold, they get plenty of snow and ice build up in the mechanisms.
Shifts ski great downhill though (A din of 13 is plenty for whatever you are doing in the backcountry, none of us are Parker White and Nikolai Schirmer has proven that a 12 din pin binding is more than enough, also Hoji would agree as well) but I am on a pair of ATK Freeraider 14s and honestly they ski almost as well if not better. With that freeride spacer those things are bomb downhill.
TLDR: Shifts are great if you have one set up, if you don't, then just come to terms with the fact that tech bindings simplify everything and are more than enough for what you plan to dish out. (I am 6'3 195lbs and fully trust my ATKs when dropping things or spinning or on steep icy stuff).
