Im with greg on this one. 30 lb leader is plenty, 40 lb only if your specifically targeting wsb.
I take my bait out of the water when the dolphins come through. They will take your bait. If you have 30 lb leader you should be able to break that off and leave the dolphin with minimal line and no spectra for him or her to drag along.
Ive hooked them before it is pretty heart breaking
