After Fuji began discontinuing many of the guides that I use to use on my builds, I thought I would give these a try. Even before I built my own rods, I wouldn't own a rod that didn't have Fuji guides. After about a year or so of hard use and some abuse, I can honestly say these are my favorites now. They're light, strong and dependable. I almost exclusively build rods for big swimbaits and these have held up and perform excellent. As of now, I have zero insert breakage, no guides that are bent or damaged or any guides that show any signs of wear other than maybe a few spots where the coating has rubbed off of the frame and I can think of more than one occasion that the guide(s) should have been damaged or broken due to my own fault. I'm not rough with my gear but all of my gear is used like tools because that's exactly what they are. I think I have four rods wrapped with these guides now and I have zero concern moving forward with them. I definitely recommend wrapping your next custom build these guides! You won't regret it!
