I use mono or old braid as backing so I am not changing out a full spool at a time. If you have a flipping rod no need to change out 100 + yards at a time, just go out in the yard and put on a 1/2 oz jig, throw it as far as you can, use a black magic marker to mark that place on your line that you want to change. Make a couple of casts, then come in and strip off that much line, plus about 15 more yards so you can bury your connection knot then tie a double uni to attach the lines and spool on the new line. I do this on almost all my reels and it works for almost all baits. I use 30 lb braid to throw most of my topwaters, so I will put a little more on that reel at at a time because you can throw it so much farther with a spook or buzzbait. Also, for my deep cranking reel, (I almost always use the same one for that) I will put more new floro on there because I do not want that connection knot to ever see the light of day. I have one of the silver Zillion 4.9 cranking reels that I use for that stuff, and that spool will hold about 175 yards of 12 lb floro, so I will normally put a good bit more line on there for long casts with bigger cranks. Another thing I really like is for my moving baits I use the Sunline Assassain line, it comes 225 yards to a spool and believe it or not, that extra 25 yards can give you at least one extra refill per spool.
