I like mine because at the end of the day I'm not as beat up. Getting old, I suppose.
I built a chain anchor as a lighter weight anchor to use on lower summer flows and found to my surprise that it held almost as well as my heavier pyramid on "normal" flows. The only explanation I have is that the "mop head" must conform better to the bottom and create more grabby surface area. Not surprisingly, the pyramid still works better for heavier flows, deeper water, longer tethering and of course heavier loads, but other than that I'd rather be hoisting a 25# chain anchor all day than a 35# pyramid for most of my fishing, if I can get by with it. That's why my anchor line is bowlined to a Quick Link, so I can switch out anchors depending on the day, load and conditions. If you have some chain give it a try and see for yourself and let the haters bounce and short drag their pyramid anchors right on by you. Contrary to popular opinion, just because you have a chain anchor doesn't mean you have to drag it.
