Been hunting them hard for probably 10 years in NW Missouri now on a permanent field into water spread and we continue to add FBs and floaters. With that said we have seen the birds really seem to love the SS decoys that we deploy downwind as they have some of the best movement of all of our decoys (white rocks, silosocks, Avery FBS and floaters). We are going to keep our white rocks at the very furthest downwind end of our spread as they stay up and open in zero to 50 mph wind. The silosocks will be set towards the upwind side of the spread beyond the kill hole fbs. The birds really, really love working to them when you have 10-25mph winds.......they wobble and move better than any other decoys hands down. If under 5mph or over 30mph winds they are not as effective IMO. We run about 1600 decoys. Abut 300 Avery FBs and TNTS, 100 floaters (Kill Hole) and will run 400 SSs upwind of kill hole and 800 White Rocks in our downwind strings. Good luck this Spring. Can't get here soon enough. Ice fishing for now to fill the void.
