I remember doing the same a little while back. So im intrigued.
I'll have to talk to my local tech about if he would mount these. He really knows his stuff and has been doing it a long time, but that seems to make him wary of new methods/products, he's a little old school that way.
What kind of footprint do these leave compared to heli coils? If I remember correctly they took up enough space that mounting a ski more than once after they had a pair on could compromise the ski. If these cant be removed at all, how much space would they take up? I can see this affecting selling the skis, if you wanted to switch bindings (and patterns) or if for whatever reason you wanted to move the mount point.
Can anyone post a pic of one of these inserts next to a heli coil, so we can get an idea of the size/differences?
