Talked to Simon G. (Rio) at the Golden Gate Rio Day last Saturday. Asked about the new "game changer" head. We talked about depth of swing and such. He says that he always uses a floating line until the water drops below around 50 degrees, at which point he starts to put the fly down in front of the fish. Otherwise he's looking for the fish to rise up through the water column to take the fly.

I downloaded the USGS water temps for the Lower American and found that it drops to right around 50 degrees for the moths of Jan and Feb. Looking back, I've been fishing with a 10' T10 whenever I'm on the water, now wondering if I was doing it all wrong

So, here's my question: how deep do you swing the American and does it change throughout the season?
