Would like to hear any tips/tricks re rudder line replacement. I have used shrink wrap electrical tube to link stainless cable end to end to pull new lines through, I'm sure there are better methods. Obviously this will not work with Epic or other rope lines and the deck holes seem to small to allow passage of a knot. Also what happens if/when a line breaks an retracts into the hull? How does one feed a new line through?

I used a vacuum cleaner to suck through a length of sewing thread.  It kept getting stuck near the end but it ended up working just fine.  I had a lot harder time threading the new line through the little holes in the bracket in front of the pedals. A cold beer and some tunes makes the whole job a lot easier to take.
