Firstly out of season im fishing on small still waters mostly rainbows, of the three out of season browns two where wee wild ones 6" and 8" obviously they will not fight hard enough to knacker themselves, a 5# over powers them very quickly, the third a 20"........ well being a bit out of condition like you said it doesnt take long to get them in

unlike a fighting fit winter bow which can make blistering run after run
As soon as i know im into a brownie, i make an effort to get him in and released, as for rainbows the longer the fight the better
Any way we've getting side tracked my query was to why
SAB felt he had to "bully the fish to prevent loss" in relation to barbless
I play a fish barbless just as i did when i fished barbed.
