Since you are already an accomplished windfoiler you will find getting up and going in a straight line pretty easy. And if you have good wind (not on the edge of being underpowered) then getting the board going in the other direction is pretty easy too. But if you are like me then here is where the trouble starts:
1. I never taught myself to ride switch. Worse, my brain would scream "switch feet, switch feet" halfway through the jibe. I really had to force myself to learn to ride switch and it's important.
2. Windsurf and Windfoil boards are longer and heavier and so have a higher MOI in pitch. So the foot placement is more critical when you do switch. And I had 30+ years of stepping back first etc. Different habits to learn.\
3. I found that having the boom in my hands connected to the mast, connected to the board helped me in my foot placement. It still feels like "the board is down there somewhere" when I'm winging. It's getting better though. I'm now over 80% jibing on flat water and about 40% in the sloppy stuff.
Good luck! I find that it's great cross training as it uses different muscles, primarily because the pumping action is so different.
