See, I can take or leave my WF3F Sylk. On one hand, distance casting is very easy due to small line diameter. However, on hot days, I've noticed that this line seems too pliable, and seems to hang up in the guides a little bit, hurting castability. Haven't had issues with the tip sinking, unless my leader loop gets crud on it (hate when that happens...) I have also noticed issues with tangling from time to time as well. But, maybe if I used a stripping basket it would be better. So far, I'm not totally set on this line. Maybe further work with it will change my mind, but until then, for me, Rio Classic is the way to go.
