First off stop with the patterned J!
Have you ever seen a real flock of birds in a J? Nope! That is a man made idea that frankly has not stood up to the test of time for me.
Shorten your longlines. If you cannot shoot the to the furthest end, your longline is way to long! I run more short lines to get tighter formations and groupings of decoys. Toss in a few singles to break it up and the lines look like a flock of birds resting.
I would keep your puddlers and divers completely seperate. Don't mix them unless they naturally mix in your area to feed.
Get your layouts set inside the top of the lines of decoys. No need to put them above the spread. Use singles around the layouts to help keep the birds eyes on decoys instead of you. Use decoys that match what you see most of in your area.
Also match what you see on the lake as best you can. If the birds are in small groupings then match that with your spread. If they are in huge flocks then you need to make it a numbers game and have more decoys as you can afford to buy them.
I normally run 4 longlines with no more than 8 or 9 decoys per line. With the decoys spread 6 feet apart that gives me a 54 foot longlines with 6 foot end runs to a clip that hooks up to the anchor line. I can clip two extra decoys on the lines at the anchor line clips if I want more birds. You want to stagger a few of the lines just enough to put the layouts right in the top of the spread. Then toss singles upwind of your layouts to make a grouping. Leave the lanes where the layouts are set large enough the boat can run in and out safely.
My trick for this is to run 4 foot droppers and use sinking mainline so the boat can run right through the decoys to the layouts. If you use dogs they can swim through droppers of 2 feet or longer and not get tangled as well.
You are moving the right direction and setting up where they want to be. Now watch your buddies. Somebody is a lookee loo. Only one of you should be watching the birds and calling the shots. The other guy or guys should be heads down, no movement, and only pick up their guns when they are told to shoot. The ducks when decoyed properly will be shot at point blank range. No need for the guys to be wiggling, looking, or getting ready. I had to actually smack a kid on the back of the head twice this year. He just couldn't help peeking to see the birds coming and was flaring everything. The second cuff to the head got the message through to him. Suddenly we all started killing birds. Lookee Loos will flare the birds every time!
