Sorry, I can't offer more on AT gear other than, go as light as you can afford. That's traditionally, some heavy gear.
Try your query at www.tetongravity.com
forum. Also though specifically a telemark forum you may try www.telemarktips.com
These sites will offer you more info than anyone could possibly digest.
Additionally, and I don't know if this is a problem with all AT set ups, but many require that you take the ski off to switch from tour to downhill modes. That's a time consuming nuisance on routes with rolling terrain.
Otherwise, tele! Free your heel, free your mind.
