For the past couple or three years I have been using the POGO SYSTEM, and I like it very well. Here's the link, if you need it. http://www.pogostickanchors.com/
I make my own cable stakes using Pogo's directions.
Most of my stakes are 1/8", 7X7, SS because I have an almost unlimited supply of this cable. When it is ok with my landowners, I often leave the cable stakes in the ground from year to year. In row crop land, pasture, or sod farms make sure the landowner knows they are in the ground and where. Because these cables can mess-up some expensive equipment. In the woods or the swamp, it doesn't make as much difference. I'll let the landowners know they are there, and they usually have fewer concerns.
I use 2" fender washers in the swamp, and most of the beaver ponds (if I need a stake at all): 1½" stakes in most woods dirt, and some row crop areas, and 1-1¼" in heavy clay -- excepting for kaolin, it will usually require a 2" .
I had Pogo make a driver to my length specs, which he did at no extra cost.
If you try this system, Pay Attention To What Pogo Tells You! Do not pound the empty driver into the ground, i.e. don't rip it out of the box when it arrives, and drive it in to see how it drives! The driver needs be loaded, that is have a cable stake in the driver, before pounding it down. If the driver is not loaded, you run the risk of splitting the tip of the driver, and having to buy a new one -- the load, the cable stake, holds the tip of the driver together as it goes down.
For what it is worth, I have used several of the well known cable stake systems, and I prefer the Pogo.
One of the criticisms I have heard about cable stakes in general is that in very hard/rocky ground, or in heavily frozen ground one must first drive a pilot hole for the cable stake, and "If you have to do that, why not just double stake with rebar in the first place?".
Everyone has their own idea and way to do things.
If I have to drive a pilot hole, and then drive the cable stake, I'm driving two holes -- just like if I drive two rebar stakes -- six of one, half-dozen of the other... , but I'm only pulling one stake (the pilot driver) as I leave numbers of my cable stakes in the ground for next year.
No, I haven't "hung-up my rebar", I still use it in/for special areas.
