I have a pair of the 14 din varient of that binding. Its a toe made by the now defunct binding company Geze. It has an upward release and the FKS Heel. It mounts with a 3 hole pattern in the toe and the standard 4 hole rossi mount in the back. More plastic in the toe, but this makes for a lighter weight. I have them on mp publics for park and cant think of a more indestructable binding for the weight. I like them more than the 916's on my Bacons.
No way dude, if its that toe, than it is a 3 hole pattern. One under the din setting, and the 2 that are visible. You drill the 3 holes, put the screw in the front hole. It is a special screw which has a tab on it. You put the toe over this screw, slide it forward, and then drill the back 2 screws in.
If you dont believe me, I can go into work tommorrow and take a picture of the jig...but as arech for 3 years, I avent seen one of the geze style toes that wasnt mounted with a 3 hole pattern.
yo man chill, ive had the 3 screw toepiece, and i know that the ones i have are the 4 screw. i dont know if they are the same toepiece as yours, although obviously not because of the different amount of screws.
The rossi jog we have for the fks just shows pictures of the 2 toes...that, and the current one. It tells us to use a 3 hole for the style toelike that, and the 4 hole for the new toe and almost every other rossi toe around. I was going by that and what i had mounted in the past.
