My biggest advice would be to concentrate on the fundamentals of position: straight arms, arms to vest, stacked position, slightly flexed knees/ankles. Since you are starting the season on the new ski, taking advantage of early season drills can help you get comfortable without the distractions of trying to run the course. Things like Seth Stisher's mini-whips and other free skiing will help you get acclimated to the handling of the ski through the wakes, help with initial conditioning, and solidify your position/muscle memory for the season. A new ski won't fix bad form. Take video and use it to verify your performance along with your experience of the ski's characteristics.
When you do start working the course, avoid trying to run desperation passes or applying any last resort heroics like standing on the tip to force a late turn. Nothing shatters your confidence on the new ski like an OTF. Slow down if you're not running things smoothly. Shorten the line when comfortably running back-to-back passes. Learn the ski before expecting to set a PB each time or scrapping to get those extra buoys. I sometimes wonder if the reward of a new ski is given by allowing it to work without pressuring yourself to do well on it. The PBs may happen naturally as a result. The best scenario is that you immediately start crushing each pass and adjust quickly. When you do, then start pushing the capabilities of the ski.
Since you are making such a big leap, I think it will be slightly different than skiers who upgrade from one current ski model to the next and experience a PB right out of the box. That has happened to me also, but after I had made that initial leap forward and acclimated to the new technology/ski design before getting the next model. I'll admit that just upgrading one model did not require the same acclimation as I described above.
One other bit of advice: run the factory fin and binding settings - at least initially. Some tweaking may be on the horizon, but do it carefully and under the guidance of as knowledgeable a skier as possible.
Let us know how it works out.
