i'm going with 65# braid this year for my 704Z.
too many rocks where i'll be angling for some bigguns.
as Crazy Al, and others have said endlessly, when it comes time
to deal with the monsters of the surf, at the right place at the right time~~~
the last thing that you want is to be undergunned and overmatched.
i ran out of line last year on a really big fish that forced me to horse her in when she began to rubb after hunkering down~~~because i had no more MONO left to give. it only took about four cranks and she was GONZO. a most valuable lesson that i hope will be rectified with the added yardage and stopping ability of braid.
as far as casting distance goes,,,,,,,,,,,,,,,,,use eeeeels or chunks.
**they're always within 50 yards of yer feet anyways, Bob**
sooooo, why not buy the big spool in 50# braid,
and fill the VS300 with 65# braid for CowTown tusslin'?
