Still have a whole bunch of confidence for the big ugly flies to work in the cold weather, as the season progresses the cold water will so down the response to the swung fly, but currently things are still rocking.  As I was witness to a fish “almost” taking one of my spey outfits.  Thank goodness we had a tight grip on the rod.  Thinking about investing in a bungee cord type of device to secure the rod to the caster.  Look for it online or at your local fly shop.  Gotta love that pull when the tug like that!  Get out and cast before liquid turns to solid.
