I just started using the 6wt coldwater floating clouser. It has a personality. Doesn't like long leaders with light flies. It is pretty good with big heavy and bulky flies as advertised.
Never used a line where I could straighten a 12 foot leader with a clouser attached on a roll cast, then take one backcast, and deliver a 65 foot cast. I can cast farther with other lines, but with weighted flies it's pretty good. Haven't really decided if I love it or not yet, but if 65 yo 70 feet is enough, it should be considered.
