I posted on this a few days ago but it seems to have vanished.
the evo comes with a solid tongue and s stiffer than the regular strucktura which has a two piece hinged tongue.
the two piece tongue is generally more snowboarder friendly.
I have a few friends that ride with the stucktura and like it.
consider a pair of the structura lights they have thermo liners and come with both style tongues.
sierra trading post has regular structuras with a gtx liner for $250
replace the liner with a thermo and they should treat you well
