We used screw in steps up until spring of 2012 and then realized that we had to purchase about 14 steps to get our stands to the height we wanted. We then realized that we could get the dual step sticks for $49 and putting them up was a lot easier than screwing in steps and safer as well. We'll still use screw in steps on trees with lots of limbs but the ladder sticks are the preference now. We had it down to a science putting up a hang on with ladder sticks and unless the tree has a lean we can get a stand up pretty quick.
Its all about preference though. I don't mind the screw in steps at all. Killed a good buck out of my stand this year that I have them on. I just like the ease of putting up the ladder sticks a little bit more.
