swivels or no swivels?

[westkrdw]

Im using power pro braid 20lb on my fenwick inline rod ( i know this is a
rod used for salt water.) and i have 17lb florocarbon leader and i use a
polamar knot to tie my lures on. it's a pain in the in the ass to keep
cutting the line to change lures. I was wondering whether i should
use a swivel. I don't use steel leaders i've never caught anything
when i had them on. Also do you think i should use heavier braid
and florocarbon.


thanks westkrdw
