I really LIKE using Super Mag Mallard dekes and have used them for years.
I know, different opinions on what's "better", big spreads of little decoys or smaller spreads of larger decoys?
It makes sense (to me) that IF I can only carry/transport a limited volume of dekes (and I usually carry mine in paper boy poncho style carriers) that the bigger ones are more VISIBLE individually from a long distance away.

And, sometimes I'll only put 3-4 decoys out, in certain locations

(werks for me!)
Plus it takes less time to put out/pick up fewer dekes. Sometimes it allows me to move, in a hurry, if I see it's better right over "there"!
In the past I've used Flambeau Super Mags and have even drilled holes and emptied the sand out of the keels to make them lighter/easier to hump.
In this aspect they were great, but a few years ago I started having them crack on me along the keels. Then the next year, more! Then this past season ALL of them cracked, and all in the SAME area!
I called Flambeau on this and they told me they DIDN'T CARE!
Well so be it! I'm not buying any more of their sh*t decoys!
I went back and replaced all mine with the good old tried and true G&H Magnums.
G&H has always made the BEST LOOKING decoys IMHO, just that their Super Mags are waaay too heavy to be humping all over!
