I think when you are plugging with top water and swimmers it can be a disadvantage because of the brightness. Bucktailing I feel is different because you are further down in the water column, so imo it doesn't matter for that. As for bait fishing, I feel its like a coin toss. Some full moons I have done well, and others I have not. Actually, I like the new moon better than the full. You have roughly the same tidal surge/pull, while you have the absense of the moon's luminescence.
Forthe moon we have on the 20th, I think they are saying it will be closer to the Earth than at any time in a decade or so. Fishing a back bay that means you will have more time near the top of the tide to fish as it will be noticably higher. It also means if you are fishing the incoming, be careful where you are. Crossing any creeks to get to your location, you may be stranded for a few hours till the tide drops.
