Four year old thread....  still getting a headache. 

 

Line, in the grand scheme of things that can fail, is pretty inexpensive.  If you get a couple spools out a a reel fill, so be it.  No need to get involved with heavy, and suspect math to do it.  You run out?  Get another spool.

In general, yes, but for $35 per spool floro, I would want to get as many respools as I can.  

 

My new "system" is to only buy lines that come in bulk spools whenever I can, which also solves the problem.  

At $35 a spool, I don't want to cut a corner, and be into backer after a month of cutting off and retying because I was too cheap to let the math go.

 

Never mind the annoying knot under your thumb.

My main concern was making sure I added enough backer to let me get two fills from one small spool. I use lighter line then most and some of my reels can eat up 75% of a spool unless I watch what I am doing.  I do some dumb math where I measure the depth of the spool with calipers and then fill with backer until I hit 50-75% full by depth.  Even if I dont know the exact legnth of my backer, I know what % of the spool I have filled and can guess pretty accuratly from there. 

 

The other "solution" is to only buy Daiwa reels, all of mine have spools with a half-way mark on them.  It makes respooling a snap.  

 

As for the knot, I back with cheap braid and use a blunt needle to push the knot into the braid and cover it with a tiny bit of electricians' tape.  I also got the bright idea to write the line specs on the tape so that when I inevitably forget what line is on what spool, I can pace it out and check.  

 

I will admit I get a kick out of fussing over things, but I think its a good system.
