A do it all shimano travela for hali rock fish and salmon?

Everyone does it different.
Lots of guys see my setup and laugh in disbelief.... freshwater bass rod, bass bait caster, leader too short, weight too small (i only use 3oz, maybe 4oz MAX) gear too light, blah blah blah.... then tap tap tap.... and I start reeling in fish   
I landed a 34" halibut, multiple 30lb rays/angel sharks at Tomales last year and a 28" salmon recently on this "laughable" setup... but it works for me!

My best advice is to choose a setup/rig that you like and are comfortable with.  Cannonball, sliding rig, 3-way, flasher, dodger, or whatever... they all work.  Choose one and modify it so that it works for you.  When you're catching fish, no one can say that you're doing something wrong.

That reminds me, I need a laughable rig donation...
