The Yo-Zuri Hybrid Ultra Soft Fishing Line is a blend of nylon and fluorocarbon, but it is specifically made for spinning tackle because of it's low memory features, which are crucial for spinning gear. Besides Yo-Zuri Hubrid Ultra Soft being more supple, it still is very abrasion resistant, water proof, UV resistant, and has less stretch then regular monofilaments. Ultra soft is available in two colors clear and a new mist green. It is available from 2 pound test through 20 pound test. If there is a line perfect for spinning gear but has the characteristics of a tough line with the suppleness that can be used in any circumstance Yo-Zuri Hybrid Ultra Soft is the perfect line.
