"Bought this line (3 weight) to fish for Bluegill where presentation is not critical but I have also used for trout as well. I have casted small mayflies and larger foam flies with no problems. It is easy to cast, smooth and accurate. I dont see the need to buy a more expensive line as this one covers my needs."
