So far I'm three proper sessions into wingfoiling, not counting the ones where the wind was too light.

The biggest thing I've learned so far is that I need what is proportionally a large movement backwards from what is my "Board in the water" stance to my foiling stance. When I want to pop up onto the foil I need to step back a good 200mm from what feels comfortable and balanced with the board just planning. If I try to get the board up without the step back it just doesn't happen. It also means that I need to time my pop up because I can't plane for long standing in the rear position.

I'm on a Fanatic 6'10" Sky surf and F-one 2200 gravity with the mast all the way forward in the track.

I have also learned that I need to place my feet where I want them to stay while flying as at the moment, any attempt to move my feet results in a big splash 

Yeah Tangogeoff, I think I got more out of my session on the eBoard than I got from the towing, but I also have friends that swear by the towing.

I definitely think it's a personal thing and I'd say to people that didn't get to grips with one method, then for sure try the other.

Good point about the windsurf muscle memory. I'm half a dozen session in now but I still revert to my old windsurfing habits when I'm not concentrating
