I'm just a 15 off, 30-32mph guy, but the syndicate & D3 are not going to be happy at your current speeds. I would start free skiing at 30-32mph with your coach guidence, then may no slower that 28 in the course. You are probably also seeing monster wakes at those slower speeds. I am on an HO 2017 Superlite CX; I can run the course at 28mph but way more effort than 30, and 32 a fun spped when I'm skiing well.
