Hey marley, I'm sure the 60m lines weren't too far off. Here's my new "lines rule":
If its less than 12kts, go with 40m lines
If its more than 12kts, stick with 30m lines (or less)
Basically, I'm setting up two sets of 10m leaders (will do more testing with 50m lines in the summer months). Also going to test 16 and 20m bridled foils from next year for the light wind option. Will post details in the spring.
