I use the "Batwing", hooking the top strap around the tree and back to the top versi-button, position the batwing on the tree so that the stand is verticle side-to-side on the tree, then I pull the stand down, with the platform still in the up position. I then put the bottom strap around the tree, hooked to the bottom versi-button, with the strap just snug, then as I fold the platform down, the bottom "V" on the stand sort of pulls the entire stand down, tightening the straps. As I said above, I some tension on the stand as I pull it down. I can then step onto the stand and make sure it's secure. On odd shaped trees, it sometimes takes a few tries to get everything adjusted correctly. The "lift up the front of the platform and step on the back of the stand" also helps lock it in on some odd trees - especially if they have a hump or twist right where the straps go around the tree. In my opinion, 2 straps are essential to locking the stand securely, and also gives the added confidence should one fail. Without the bottom strap, the platform can move side-to-side easily on smaller trees.
Lone wolfs are now the only stand I use as they are secure and quiet and will hang solidly in a variety of tree shapes and angles.
