The fact that the EZ lags are superior is only part of why that type step is better.I use the Cranford EZ steps for all presets. I am sure there are other companies that make good screw in steps now, but back when I bought the 100 or so that I have they were considered the best. I just have the EZ rod model I guess you would call it? Looks like the ameristep ones but they are much thicker and the threads go all the way to the end, making it much EZr to screw them in. One thing to note is that if you are using them while you are hunting on a run and gun type set up and are wearing some gloves that have that silicone type grip to them, it can be frustrating because the glove will wont to bind up while you are screwing them in..Not sure if that makes sense or not...The remedy for this is just cut a small piece of PVC pipe and slide it over the steps while you are screwing them in..it really does help. If you are using them as a platform just make sure to smack them a good couple extra turns to kinda "lock them in", if done right they won't move at all while you are on them.
Cranford steps are expensive so if you are using them for presets, its good practice to back them out a bit at the end of the season, or before you know it a couple years go by and it becomes apart of the tree haha
Steps that fold at the lag can be buried deeper into the tree that the rod style.
Once the rod style meets the tree during the screw-in phase, you are about as deep as you can get them. If you didn't start the step square to the tree, you won't get them in all the way.
And if the tree has a bump or knot, you won't get them screwed in all the way.
Rod style take up more space (than the folding lag style) when you make a full revolution during screwing. Sometimes you get partially screwed-in and then you get "screwed" because, as the step is going in, it ends up having a branch or something in the way which causes you to unscrew and relocate the step.
Wow, every time one of these threads pops up, and I chime in about rod-style steps, it reminds me how much I absolutely hate the rod style.
If you can legally use screw-ins, then buy the deluxe style and if you need many, many steps, then go with bolts.
