As for diver decoys...the buffys are great for GHG- actually, havent found any better. I have some super mag G&H bluebills that I LOVE but they are now $135 for 6...guess I will never be able to buy them again. I love my foamers for my line rigs. Only problem is the bodies will hold up to being shot, but the heads do not. The pellet going in is a small hole, but it is like a hollow point going out- it will blow the whole backside out. I want to make a mold so I can make replacement heads out of expandable foam so they are solid. I made 10 cork redheads three years ago, and they are the greatest. The most durable and unsinkable, just need a little paint touchup now after 2 seasons. The cans and redheads cant resist. Only shot one can before I had them, and shot 23 over the past two seasons. Good results. I think birds like the homemade as they may be a little different than the factory spreads they see all day, everyday.
Now I am a garage sale guy...I have been buying old foamers and burlapping and repainting. Something to do while we (my wife, not me) watches reality tv at night... Got lucky and found 6 at a sale this summer for $10. Now they look great! I will try to post some pics as soon as I can.
Check out some of the other forums...they have great instructions on how to make you cheap decoys look great for any type of bird. Some people are AMAZING at what they do!
