Well after breaking most of the A/T bindings on the market I have decided to switch to a dynafit binding. I will be using the binding with a Scarpa Spirit 3 boot. I have narrowed the binding choises down to the Dnyafit TLT Speed Classic, TLT Comfort and the Vertical ST. This set up will be used only for touring. I am 6'0 , 180lb and typicaly ski fairly hard. Anyone who has been on any of these bindings and could give me any advise would be very appriciated....I know I should put this on tgr but I do not like that fourm.
