Re: which one you will choose ?
The magnums will give you a little bit more visiblity as they will appear bigger on the horizon, not by much though. But they'll also take up more room in the boat whereas you could fit more regular sized ones. And 21" long is a fairly good sized decoy you figure just shy of 2 feet long is already a good size plus you're getting 5 more so you can spread them out more.
Just keep adding to your spread over time till you find the right size that works for you.
1st Im in charge, and if not Matt is. Your job is to sign checks, tell us we're doing good and open your case of scotch after a good day. 2nd my fee. You can keep it, all I want in exchange for my service is the right to hunt all the drakes. A male. Buck only. Why and how are my business. If you don't like it, go alone. Set up right here or in a swamp or in the middle of a noshoot field for all I care. I've been on too many duck hunts with rich dentists to listen to any more suicidal ideas. Ok?
