I would be willing to bet that you tune your rig in the spring and let it go for the balance of the season. Am I correct? Or perhaps, your rig has been standing for several seasons and you have not touched your turnbuckles or pins for a couple of years other to inspect them. I know a lot of boats out there like that. These are not for you, they are for the sailors and racers that tune and adjust and retune as conditions warrant. Just because they do not fit your requirements or needs does not make them a bad product.
$3.25/ea. ?? Not very expensive if you ask me.
Like I said, they are used on the boat that I crew on and they are very convenient and have never given any problems and have never opened up or snagged etc.
