It depends on the kinds of winds you get in your area. Where I hunt, there's just too much wind to run socks for canadas, at least big honkers. If you have large numbers of lessers, they might work better, but I have always found socks to just move way too much for me and flare more birds than they finished. I would look into some silhouettes if you're going to go B&W's. They work great for traffic hunts and we always placed them for highest visibility and always upwind of the more detailed decoys. Another choice would be to take a look at Big Al's "Take-em" style silhouettes. They are a nice, true to life darker color, work GREAT for traffic hunts and you don't have to worry about having to place them upwind of your "nice" decoys because believe me, they'll finish birds. They are also very easy to set up and take down and for the money, I don't think you'll find a better, more detailed decoy out there. We're gonna run them this afternoon as a matter of fact on some resident birds that have already been hunted pretty hard and I have no doubt we'll get into em! Here is the link for Al's site. Good luck! http://www.bigalsdecoys.com/
