Not true.... Even with a 4 foot leader see how many fish you have hooked outside the mouth. Even when I throw a 3 foot leader I accidentally floss half my fish, especially with corky/yarn. Longer leaders with bait makes it tougher to floss and if that is your point I do agree. Coho hang out deep and you could probably floss them with a 2 foot leader. Just my .02.
