George,our slot for F-1's is 15" and this stock is now 9 years old so we are adding 1400 lb of Black Bass this winter to shake things up. My biggest Coppernose to date is almost 3 lb. The reason I can't give you an accurate weight is because I weighted the fish on a spring scale and can't give you the ounces. Try that on a #3 fly rod! This summer I found a three pound bass dead from chocking on a one pound bream. PS. Ketona Lake is 10 miles from my house and is a cesspool.
