Weight is very important to me, I don't want my decoys to be heavy as lead. This rules out many of the new "made in China decoys" on the market. This is why I use old style G&H floaters, very light weight, good lines, finish birds no problem, very durable, easy to repaint if needed. As far as removable heads, very nice during the off season for storage. If you don't like removable heads, use some plumbers goop, then they are "non removable" guaranteed to stay put. No problem!
