3T Stylus seat post with oval carbon braided rails????

Is anyone running the above? The larger 7x9mm rails seem too big but it’s really really close. Are you supposed to clamp it down so the rails move slightly to fit or does it just not work?

I’ve read all the comments about optional bits for the Palladio/Ionic but nothing to say the Stylus wouldn’t work. Just seems unbelievable to me as it’s an extortionate LTD seatpost and most owners would want to run carbon railed saddles.

Although I couldn’t see anything to say you could do it, the fact that they don’t sell optional bits made me assume it would be fine e.g.

Thanks for any advice.
