Oldmanskier I've used the FT setup above that Wish added, this season was an experiment had an issue body related i wanted to solve with the project but now its not me. I maybe can help you after all tries and error I've done this summer. i started with the same as you two Fulltilt boots Intuitionsliners the shell had an tongue that allowed me to flex forward but with resistance that u can change, i clamped the boot into an non release binding and of we go! deepwaterstarts almost impossible! manage to get up after 10 or more attempts experienced rly nice offsides and first time in my life a felt the term smear /slide that Rossi, Jay and others talk about. but with two mounted hard-shells i had hard time to initiate turn on my good side. with regular bindings when u lean forward over the ski u bend/raise your back foot ankle but with this setup when u try move forward with the rear leg and hip the only thing you bend is the whole tail of ski i think that caused an massive increase of the ski rocker that led to the easy offside smear /slide ! later i changed to radar vapor boot back on the non release binding that solved deepwater start and problem to initiate some turns espec on my good side. but now to other issues with our setups spec mine , my foot is 1,7 inch above the ski +the thickness of the intuition liner imagine that u stand on skyscrape and your ski is on the bottom of the scrape to get your ski on edge u must first lean the "scrape" that is like an lever arm very slow pre turns and hard to get the ski fast on edge. i tried to bolt the boot direct to the sequence plate yes it was better but still very slow edge change and hard to get on edge, i planned to trim down the boot to an thin layer so i almost stand on the sequence plate with the intuition liners and mold an slim carbonfibre construction around the boot so i have something to anchor the boot into the plate with, alternative was some modified reflex system but then i don't know if the boot lose its form cos of the weak/half open botom of the boot. later on i removed the upper cuff and trimmed down sidewalls just above the ankle my skiing was improved after that. But you cant do that at least not remove the upper cuff then u lose the ability of the boot that helps u out with your injury so my tips to you keep your front boot or try to get an full tilt boot same as mine but trim down the botton of the boot to almost nothing or open botom and on someway solve how you shall attach the boot to the skiplate and sugest that u use an soft boot back /rtp max an softer regular hardshell reflex or other brands. Happy new year and gl next season with your sking and confiurations.
