I have an old brown Type III that must be about 20 years old. T-3's get very little press and I seldom hear of anyone fishing them. I like it because it gets the fly down quicker and allows me to fish a little deeper water than my intermediates. It is time to replace the old beater with a modern steady sink line. I am looking at an SA Mastery Uniform Sink Plus in a 5wt. Any thoughts on this-is there something better I should be looking at? I have no experience with steady sink lines but can see that I would probably be better off using them than what I'm using now.
