So I rode the foil a lot more this weekend. I tried it at surf length and I felt that the normal wakeboard wing that I ride at 13mph at 75 feet didn't have enough lift for surfing at 10 to 11mph.

I'm tempted to get the Infinity 76. For surfing, I didn't want to go nuts, so I only filled the port 1100 bag. I did it with the 24" mast. (When I tried surfing with full ballast and the 30" mast, it was too binary as I got in the pocket and I got ejected immediately.)
I was able to briefly slack the rope, but not enough to keep it going. So, it seems my options are more speed (silly for surfing), more ballast, or larger wing. Thoughts?
