Progression requires experimentation. I want to build diy boards with no tnuts. Tele bindings for years only had three screws per binding and people, but skis are beefed up in the mounting area. If I add another layer of glass where the touring bracket goes I think it will do the trick.
Side note, my first split snaped across the touring backet while skinning through a dip. The board had an "air core" where the core has channels milled out between the bindings not good for a split but I didn't know untill the board was cut. It lasted three years.
I built a dynafit soft boot this summer so a different hole patern is needed.
