I've got a pair of 170 cm 2013 Head Supershapes (pic below) with the Speedflex Plate 13 and SP12 demo bindings. They're a little stiffer than I'd like for drills and all-mountain skiing, and someone at Head advised me that I should swap the SP12 for a Freeflex, since the latter's sliding action would allow the ski to flex more readily (plus, it's the binding the ski was designed for). The plate is predrilled for both the SP12 and the Freeflex's, so this is easy to do.
My plan was to get the FF14 (I'm 150#, and use a 7 toe/8 heel), but I just saw a great deal on a new 2015 FF16 ($130 incl. tax+ship). So, questions:
1) Is the freeflex action the same on the FF14 and FF16 (i.e., will they have the same effect on ski flex; it's certainly plausible they could have set it higher on the 16)?
2) The FF16 is generally touted as being a better binding than the FF14, if you fall within the 16's DIN range (which I do). But it weighs a half pound more per side; not sure if I'll notice that in the moguls. Any general comments on the FF14 vs. the 16 for an aggressive all-mountain skier? I gather the FF14 favors release, while the FF16 favors retention (twice the upward force needed at the toe, no diagonal in the heel). Don't know how their elasticities differ.
3) When I attach the bindings to the plate, should I use waterproof wood glue (like one would when screwing directly into the ski) or, alternately, blue Loctite? [Yes, I'll be having a shop do a release check; but attaching to the plate I can do myself.]
