Ive been looking for a good light line for my spinning gear, for fishing a very clear water lake that I've been fishing for several years. I've been using 6lb mono in different brands for years, but always on the lookout to improve my line. Many have recommended this Yo Zuri Hybrid line here on BR. I ordered two spools, one 6lb and one 4lb. I've spooled the 4lb on a med spinning rod. This 4lb has a break strength of around 7lbs or more. Fishing small plastics. Grubs, 4" worms, tube, etc, this line handles very well. Great casting, and excellent knot strength. Good durability, and abrasion resistance also. I haven't used any line conditioner, and I don't think I'll need it. The line handles good as it is. This Yo Zuri is affordable also. As for being more sensitive? That's hard to say? I'm using a sweep/ reel hookset, which works best with this line. If you need a lighter line for clear water fishing, this should work well for you. Im liking it so far, and plan on fishing this one until my lake freezes over this season.
