Iam using a 5wt 8' rod with 5wt wff line and am getting 20-25ft cast most of the time.would going to a 6wt wfline help me or is that going to mess up what I've got now.I went out late this afternoon on a small local lake that the city han stocked for a kids fishing tourney about 3 weeks ago but it is so hot down here nothing was biting .no one was having any action ,not even the bait fishers
