Interseptor,
I had one, used it extensively. The system is fine, however, you can do the same thing with either rapid rails or lone wolf sticks- the difference is you are setting up four steps at once with the rails or sticks, and you have to do four hang procedures to equal the rails/sticks with the stepladder.
I can move around limbs with RR -which was the big selling point of the stepladder- "wind your way around the limbs", except the most extreme cedars etc..and I don't hunt where there are many of those type trees to climb anyway..mostly hardwoods here.
