When I had a 6.0, I riveted the telocat clip to the bottom of the foil and then bent the post upward. Also drilled a retainer clip hole in the rod to secure the rod and wind indicator. After I put a spinnaker pole on the boat I had to remove the clip for the pole would go under the foil.

So in hindsight I would go with a top mount clip. But ... I am no longer comfortable with drilling additional holes in the center of the foil. I have seen 4 or 5 of these foils fail. Typically they fail because of a fitting or dolphin striker rod issue but I recall seeing a foil folding. This is not pretty.

Good luck.
