Interesting. I can tell you don't use Power Pro. It is a four strand brand that is not very round. It didn't do that well on casting distance for me. My 2lb Trilene XL can cast a Panfish Magnet slightly farther. It just didn't come off the reel smoothly. Yesterday I took it off and replaced it with Trout SOS 2lb. Haven't had a chance to use the SOS yet because it is raining right now.
