save yourself money no matter what line you use. many of you probably already do this....but for thos that dont...

spool on, about 2/3rds of your reals capacity, a backing of 16# to 20# quality line(like all the fly rodders do). Then, fill your real the rest of the way with your favorite line. this way you only have to change out that 1/3rd each time. make sure you learn a good line-to-line knot for obvious reasons. keep that not as low profile as possible. practice makes perfect. i've not yet lost a fish due to knot failure at that join of lines. works for me...
