I use 10 lb or higher Nanofil with a 12 lb Invix leader, tied with an Alberto knot on spinning setups. I don't go lighter than 10 lb Nanofil because the smaller diameter ones cuts through the leader. I don't fish everyday, and not for more than a couple hours at a time. No issues with wear, but I do reverse the spool at the start of the next season. I did have a problem with direct tie to lures, so started using the fluoro leader.
