Back to the topic at hand I have been using my fimblesaver enough now to have a solid opinion, two thumbs up. I was pleasantly surprised when it arrived at how it was built, with a length of Sirius cord doubled, loop over the large thimble and then wrapped with the white/green cover they traditionally use. This design creates a broader sling, almost strap-like, rectangular instead of round. The steel thimbles are great friction is not noticeably different then a standard ring-ring. I tend to worry less when retrieving from the ground that it will get damaged on its way down. I also am very satisfied with the retrieval success rate which so far has been 100% thus far. Haven't been stuck once. Also I am currently using Samson Vortex line, which has a larger diameter @ 1/2 inch and I've found when I retrieve remotely the tight eye splice won't make it through the small thimble far enough even to catch on the retrieval ball, which leads me to believe I'd be able to get it down without the ball. (Although I haven't had the courage to test this theory in day to day work, which would certainly be the time it passes through leaving my fs up top.)
Over all I am very pleased with this device and would recommend it to anyone interested in it.
