Same 12lb Maxima...if you can land them quicker, isn't that more desirable. If the fish still eat the fly why would it matter. I don't break ANY off, I land them VERY quickly.
Does it make you a better fisherman to nymph with 4lb test and loose flies and take 10 minutes to land a 2-3lb trout? To me, anything over about 2.5 minutes is unnecessary.
10lb Fluoro for stillwater chironomid fishing works fine...when they can sit and stare at the leader. In running water probably not much of an issue....
Why would you not use the strongest line you can get away with to land the fish in the quickest manner?
Sorry the idea of "overkill" is lost on me
Just an opinion
