Funny.And it could be mounted inverted for the southern hemisphere folks .
I am not a 'slinger' unless it's side mount.
Up with the Hydros pro [simple harness], inverted with either of my 2 wings, just works for me.
I will post photos when either is next setup.
Found one: The 2nd stage for the pony was a Aqualung reversed going under my left arm , it is playing up so an easy fix is this setup, trim weight on the right side, pony on the left.
