Great, well informed and concise video! I'm planning on trading out my Ozone Mojo 3 and get the Ozone Ultralight 4 with this harness as I intend to do some travelling with it longterm. (After the virus situation settles down of course, likely in 2021 now) Do you have a quote from Ozone for the Ultralight 4 glider by chance?
I use this harness (33L version) with Ozone Unltralite 4 size 21. It fits well inside the bag alone. I also pack lightweight reserve (Skyman Unltracross 75), compact helmet (Petzl Sirocco 1 size 1), Compact Down jacket and gloves - all this stuff fits, but very snug. Probably about 80% of space is taken by the wing Ozone Unltralite 4 size 21. That wing weight 2.2 kg. Ozone Buzz Z4 wing smallest size weights 4.8 kg, which is more than twice bigger than my wing weight which means more than 2 times more material and probably volume. I think there is no way any size of Ozone Buzz Z4 will fit even in the 33L harness. I have small size Ozone Jomo wing and it weighs 3.6 kg and the volume of thins wing in packed condition is almost twice bigger than my Ozone Unltralite 4 size 21 and there is no way even 3.6 kg wing will fit this harness. So again I'm sure Ozone Buzz Z4 will not fit this harness.
Yes, you should use this harness with front mount reserve. Reserve should be mounted with Y-bridle to the carabiners (or soft-links whatever you use to mount your wing to the harness) and packet inside a front mount container (front mount container is mounted to the carabiners too).
You bet! When in backpack mode, both the 26L and 33L version will fit any speed wing including the Fazer 3. The OZO harness dimensions are the same for both models.
You could probably find a way to put one on there, but it does not include the buckles for it. Stirrups are meant for getting back in your harness, which isn't really a problem with a split leg.
