I was using the aero for awhile till i got the sit drag. I found that i kept loosening the belt of the aero and using it like a sitdrag. I think that was inspired by DaveT. That started the leaning process for me which leaning always felt like a better position for shooting and filming. The sitdrag just filled in the gaps for what I was looking for i.e. Lightweight, no to minimal hip pinch, comfort, and simplicity in design without the leg straps. I found leaning was ten fold more comfortable with the sitdrag and as it was easier I found it just could be done longer. Before saddles it was climbers and hangons which felt way worse on the back.
This might seem odd but i hunted with a buddy on his property last week in a hang on. After 20 mins or so it just felt odd to be facing away from the tree. I had brought my sit drag and just rigged it up and used the seat as a platform instead. Facing the tree was just way more my thing I guess. Sorry if that sounds weird lol
