Okay. This is my input. I'm a goose hunter. And I've guided and hunted strictly for specks for a while.
The water makes a HUGE difference. Maybe not on the perfect condition days, but on the blue bird, no wind, nothing flying kind of days... 0 inches of water is the ticket.
Next is the calling. Calling can totally define the way a goose hunt will turn out. You may have a descent caller that kills singles and doubles. Then you could have an excellent caller who can call groups of 20-200 in the decoys.
Concealment is a great deal of it. You need to be covered extremely well to kill specks on a consistent basis. Also being concealed and good calling will allow you to kill less juvies and more generals.
Here's some photos of my spread right now. I killed a limit on it this morning.
