Partial line change?

[WildmanWilson]

Wondering if any of you leave some old line on the reel to save money? With the high cost of fluorocarbon seems a good way to stretch a buck if it doesn’t affect performance. If so is there a certain knot that’s best to join the old and new?

[MN Fisher]

I don't pay a premium for FC line. I've been using Stren Flourocast for years without an issue...and it's only a buck or two more than Mono per spool.

 

The joining knot would have to be deep enough on the spool to not interfere with the casting, especially on Spinning Reels. Figure your longest cast, add 15 yards to that, and cut back that amount.

 

Blood Knot or Double Uni Knot would be the best for joining lines far as I know.

Yes. I'll even put old line on a new reel the very first time (backing). It will never see the light of day if you've got enough line capacity. I'd use a double uni knot for similar size lines, or alberto if you're going old mono backing to braid.

Only replace the working 75 yards of the working end on all my reels

Yup, I leave enough braid on the spool so the 150 spool fills it back up. I used a Used a double uni. When you get down to that knot do it again. 

[Dirtyeggroll]

Yep. I use cheap mono backing for most of my reels and then put 75 yards of the good stuff on top.

 

I join them with a double uni knot only doing 3 turns per knot.

I do it with most of my reels that have fluoro on them. No reason to replace 100+ yards of line when I only need to replace 2/3 of that. 

[LionHeart]

First 40 yards on all my reels are cheap flouro.  I join to main line with a cinch not on each side and never had an issue with knot breakage or any weird lumps on my spool.

I wish these line manufacturers would stick a thin piece of paper or something for every 50 or 100yd of spool so we can easily tell how much line we're taking out of the spool.

 

Hate being left with like 30yd of spool and going to waste.

I use Sunline Sniper on several baitcasters they come in 200yd spools so I just figure out needed amount of backing and spool on last 100yds with Sunline which in turn cuts my cost in half per reel. I just use a uni-uni knot with 3 wraps.
