Replying to Does weight really matter that much?

so i really don't know a whole lot about touring but i really want to get into it. I'm looking into getting a new setup, fatter than my resort set up which is 4frnt devastators with griffons. however, i want to be able to ski my new set up in resort though (my home resort is alta) so i was leaning towards more of frame bindings over tech bindings.

so my question is, will this added weight from the frame bindings really make that big of a difference when i'm touring? and if i did end up getting tech bindings, how do they do in resort skiing?
