Tried my new 15'er today. I had trouble getting the line to pull the fly up out of the water. (Airflow delta) Does the leader need to be 15'? I had a pretty stiff head wind and ice was forming on the guides and the line. I think I was still underpowering the cast though. My entire instruction up to this point has been the Winston spey video. My best cast was maybe 60-65'. I had a lot of casts that ended in the fly stopping the line like an anchor and killing the cast. Best guess, is it style or power I screwing this up with? I only cast for about half an hour as I got tired of dodging giant chunks of ice.
