the thinking with the two line system is two-fold:

- get the tack of the sail out early to ease the hoist
- adjust the spin tack (distance) if needed

My personal preference is the single line system for ease of use. For some reason I regularly forget I have to pop the tack line to complete the spin douse, and that might make me have to come inboard to complete which can result in "issues" with boat stability.

Anyone know how to rig that little ring on the spin sheets to suck that last part of the clew in the sock? I saw it on Alex's F18 and it looked cool.
