My new genoa came with wool yarn tell-tales installed but they all stick to the sail. In my first sail, with wind up to 7-knts, they do not move at all. I was able to reach several of the ones at the lowest position and they would go right back to the same spot like they were spring loaded. Anybody have any tips on what can be done to make them work? In the past I have used the tape type instead of the yard type. If I decide to replace them, any suggestions on how to remove the stick-on disks?
