The braid spool does not hold a lot as its so shallow and you dont want to fill it level like mono as you will get bunches pulling off.I got 230 yards of Spidercable ez braid on mine ,its 30lb but is thinner than the 20lb I got from china.You wont need mono backing as there are a couple of holes in the spool to atach the braid through so it can`t slip around the spool.
