First off let me qualify my remark about using a 4 weight, I'm talking river trout that put their all into a fight and then have to pose for mutiple hero shots, fine most of the year just don't think so this time of the year course I might not know as much as some on here have only flyfished the central pa limestoners for around 40 years, was lucky enough to have cut me teeth on Spring and Penns and Fishing creek and got to watch my father who taught me a lot sit and converse with George Harvey on more than one occasion, talk to some people other than me and see what their thoughts are on what stress can do to a fish in higher temps, was only saying that IMO a 4 weight is kinda wimpy for river trout this time of year, think we owe it to the fish to play as quick as possible but hey maybe I still haven't learned how to play a fish correctly.
