I can tell you, the VO claim of 30mm setback is a stretch. Take a look at the design. The cradle which supports the seat rails is a curved design, so while technically it may provide 30mm of range, when the saddle is positioned as far back as it can go, the angle is pointing the saddle nose up by about 30 degrees. It’s definitely not possible for anyone to ride with the nose sticking that far up. Not even close. Bringing the nose of the saddle down to anything even remotely rideable moves the entire saddle forward, shortening the setback.

I bought a B17 and realized immediately that I needed a lot more setback because of the short rails on the B17. I bought the VO thinking it would get me there. It’s a total fail. While I cannot claim to have specifically measured, IMO the VO barely offers more than my 20mm setback Zipp seatpost when the saddle is in a level position. As a result, both the B17 and the post are sitting on the shelf.

I’m gonna take a look and see what Nitto has to offer.

Edited to add: You’re gonna want to stick with a clamp design which is adjustable from the bottom. I tried the B17 on a 25mm setback Specialized post that adjusts from the side, but the stiff leather skirt of the B17 blocked the clamp/adjustment Allen head, nixing that idea.
