Has anyone had actual experience in using these? I am getting ready to redo the halyard eye on my jib using a fid kit and am wondering if the splicing nut would be the answer. Not that making a new eye isn't good practice, but this product seems to be preferable to trying to splice in a new eye in an older halyard. By older,I mean about 3 yrs. Still in great shape, but I didn't realize I needed a pendant on the furler and have worn the old eye a little. While I have the jib down for maintenance, I plan to redo.Any experience with this would be appreciated. I am not trying to sell it, and have no personal interest in the product, just wondering if it is worth using.
