706Z and fireline question

[Joe]

I'd say about 30%-40% of the spool should be backing, depending on how full you like your spool.

I know the spool takes 300 yards of 20# mono which has a diameter of .018
If you divide the diameter of the Fireline by the diameter of the mono - then subtract that percentage from 1 that is the % of backing you need to fill the spool.
For example:
300yds X .018 = Full Spool
Say your braid has a diameter of .012 (hypothetically)
.012 /.018 = .66
1-.66=34% of spool backing needed
.34 X 300 = 102 yards of 20# mono backing needed

Joe; That's some info you just gave us. Thanks. Jake.

300 yards of 20lb fireline will fill a 706 with just enough mono to fill a spool, trust me I've done it. Fireline is much thicker than most braids, also breaks substantially higher than its rated form, 30lb fireline has a diameter close to 20lb mono.
