Glad you got out. It is not the number or size of the fish that make for a successfull outing. The question is did you enjoy your day. All fishermen have days that we have great catches and many that are not stellar on catching. Sooner or later that large catch day will come.
Prior to buying a new line clean it and use some comercial cleaner treatment on it. I sold fly fines for years and rejuvinated many throwaways. As long as they are not cracked it is worth a try.
