I'm getting my ass kicked here! XD
Maybe it's the transition to saltwater.

I've managed to catch a few 30lbs Mahi-Mahi and some other small fish, but that was very spotty and I can't seem to hook anything bigger.

I don't need a step by step how to, but some tips on bait, hook size, do spoons even work here?

Thank you

I used lift&drop with the first speed to pull the line in and DAKINO QRT5 size #6/0.

p.s. don't check the flyfishing, this is modded.

You need to write a guide.

I'm serious. You can print in online somewhere. You'll be famous.
