Hi Hayden, unfortunately, we don't have any parts to attach different power straps to the cable of the Ridge Pro mechanism. You could attach a booster or similar non-Hoji-mechanism strap by riveting it on either side of the bulge from the Hoji mechanism.

Hi Tyler, there is no mount plate that would require tapping. In fact, despite the printed topsheet recommendation, we'd recommend drilling them 3.6x9.

Hi Peter, you'll need a 19.5mm screw, which we don't have. You could grind down the 21.5mm Pozi above.

Hi Peter, the fit is overall quite similar to the F1 XT. The one thing is the Crux might fit a hair shorter than the F1 XT. If you fill out our Boot Fitter, we can get you more personalized recommendations.

Hi Justin, hard to say for sure, but I suspect they wouldn't make much of a difference in stiffness. If you have too much room in the stock liner, the 9mm could improve the fit, and improve how they ski.
