About 6 weeks ago I purchased a spool of Rio Gold WF4 fly line. I finally got out on the water with my 4wt and after about 45 minutes I noticed my casts behaving oddly. I suddenly was throwing horrible taling loops and it seemed like there was a kink in the line near my leader connection. When I reeled up I found a full circumferential crack through the PVC coating of the line.
I called Rio and they were super to deal with. I have a new line on the way right now. I will be sending this one in for them to look at for quality control. Just thought I would post this and let you know. I love the way the line handles and I have been nothing but impressed with the customer service at Rio for the way they have handled my needs.
