I'm a newbe to the spey game and was wondering if anyone has used PowerPro braided line for backing on their spey reels? I have an Okuma 10/11 and with a Rio 9/10/11 Windcutter it doesn't leave a lot of room for backing. My main concern is if PowerPro is too abrasive? I want to use the 40#. It looks like it's less than half the diameter of 30# micron. Any thoughts or suggestions?
