I've used the lone wolf alpha hang ons for the last 4 or 5 years. I use the easy hang J hook, and on occasion leave the strap in the tree. I've foud that the J hook / one strap alone will allow stand to shift from side to side if you shift your weight quickly. I've gotten into the habbit of carrying an extra strap, just hook it on the bottom versa buttom with the bottom platform folded up. It loads up the strap when platform is dropped. May take an extra 30 seconds but makes for a safer hunt. I also always check to make sure the J hook is fully engaged in the stand. My hunting partner hung his lone wolf alpha stand in the dark 2 years ago, got in, and 15 minutes later, the stand took a dive. Only conclusion was that the J hook was not fully hooked in and when he got on, it slide off the hook. Fortunately he was wearing a safety belt. Just my 2 cents.
