Too much work,lol. I never had an issue before till this tree. Not sure what type it was. Maybe a hickoryif you want good bite with your batwings, only thing I can think of is adding a versa button/lonewolf strap or rope mod. Lash it to the tree and get it pushed down the tree..locked down, like a stick. Get your weight on it by either using a little aider(accessory cord/sling loop) from the bottom, or by getting above it and putting a foot on top of the bar.
Then work on your platform cam
