Estimating Monofilament Backing When Using Braided Spectra
How much monofilament backing will i need beneath my braided line top-shot?
This is a nifty mathematics calculation on how to estimate how much monofilament backing you will need to use with braided line top-shots.
In this situation we are using a Shimano Sustain 5000 spool which holds 200 yards of 12 lb monofilament. and we want to use a 150 yard top-shot of 20 lb braided line.
How much monofilament backing do you need to fill the spool space?
What we know
-
spool holds 200 yards/ 12 lb monofilament
-
12 lb monofilament diameter = 0.014”
-
20 lb braid diameter = 0.009”
-
We have 150 yards of the braid
Calculate this
Now that you know how many yards of monofilament you need, how do you measure the 100 yards of monofilament?
Use a mechanical line-counter like the one in the photo to the right.
