Last year I started using binding inserts to utilize one pair of bindings on multiple skis. The system has been working great. Between Emily and I we have switched bindings about 50 times, with one spinner that was easily fixed with a heli-coil and has been great since. Last year I used Quiver Killer inserts, switching to Binding Freedom inserts. I’ve come to prefer Binding Freedom’s offering, plus they’re constantly coming out with new tools to make the job easier and faster.
The installation process is exactly the same with both products. They’re actually identical in every way and I’ve got one pair of skis that utilizes both. They’re both quality products, your choice boils down to personal preference. If you haven’t tried these out yet I highly recommend them.
