I have a sink tip line but use floating line 95% of the time or more, especially when fishing for bream and bass. But its like using a pig and jig or plastic worm, not as much fun as a Zara Spook or buzzbait but frequently more effective. I would probably catch more or bigger fish sometimes if I used the sink tip more. It also depends on where the fish are and water conditions. It's difficult to get a fly down to fish 20 ft. deep.
