Rosenbauer on Sinking Fly Lines

In his latest podcast, Tom Rosenbauer tells everything he knows about sinking lines.
“I see the purpose of sinking lines as allowing you to retrieve a fly at a lower level, whether it’s in a lake, or a river, or a pond, or the ocean. The problem with a floating line, even with a weighted fly like a big tung-head muddler or a conehead woolly bugger, is that after you make your first couple of strips the fly gets drawn to the surface.”
