Got a little fire going while I decompress form today's bust azz homework .
Still for me I like the 4' deep or so pockets for salmon, not so much steel.
Those fish in that depth are aggressive fish to me. They try and hold their ground until pushed out by other fish or pizzed off from a fly in their face. Granted as db said, you may have to walk ( I don't wait ) to find fish moving into these places.
It to me is swinging a big ugly with little or zero weight 101, watching a fish move to grab the fly is money !!
I totally understand the heavy deep pockets, its cover and congregation for more fish. Sadly it draws more fishers and some don't play fair, hence I avoid them. That's just me and how I like to target salmon, I like seeing the strike of a king :)
