The all-in-one is a different style of whoopie technology. Normally the whoopie runs from the hammock uphill to the adjustable side and then the strap.
The AIO is upside down by design, which puts the adjustable end towards the hammock, with the small eye being connected to the strap.
No need for the marlin spike hitch.
Hope that helps.
