Air/water temps when fishing will play into line selection too. Note that Sol fished a braided line this fall when it was warmer, then switched to mono later during the same fall when the air/water temps dropped, also Zog stated the water temps were running 37 degrees during his 2 weeks on river. He fished mono, as did Sol & I'm sure Nick too.

IMHO, its MONO only when its gets cold. Braid will lead you into a frozen "charlie-foxtrot" mess.
