Uncanny really as I was just looking at my windsurf harness today and thinking "would it work on the cat too?". I'll try it this weekend?
Otherwise my hobie full "auto" harness is really good and comfy but must remeber to tighten the thigh straps first to save the family jewels!!
I've not heard of a ball connection though, do you need this for the windsurf harness or will normal J&H handles do?
Cheers Phil
