RIO Powerflex Plus Trout Leaders are the strongest trout leaders ever made, with tensile strengths up to 20% more than regular leaders. More knot strength, abrasion resistance and suppleness than ordinary tippet. It didn’t seem to have good stretch/shock power. It can be hard to tell what kind of value you are getting in a spool of tippet. You should also consider the breaking strength of each brand of tippet. The RIO Fluoroflex Plus Tippet - Guide Spool is made from 100% fluorocarbon, making it the strongest, thinnest fluorocarbon on the market. I know lots of guides love RIO, and because of that have tried it several times, but Orvis Super Strong (the old stuff) and Trouthunter just seems to worked better. $25.00. Available in 30yd and 100yd spools.
