This flossing theory has a few major flaws. You would think that the long leader gives you a better chance of flossing the fish but think again. For one, in order to do this you line must be at the same level as the fish. Secondly, what are the chances that your long leader will enter the fish's mouth. Finally, I like to ask you, have you ever hook a fish at the end of the drift? I tell you that I have and many of my catches are at the end of the drift. So how in the heck the fish is being flossed if it is right behind your leader? Think about this and I'll tell you my theory of the extra long leader. I do use extra long leader and it works any where and for any level of river dept.
