IMO - the best advice is to catch up with the local foiling crew - in Perth that's about 20 strong with most hanging out at either Melville beach or Pinnaroo Point up north , its easy for a more advanced kiters to give any new or developing kiters relevant tips to help them advance quicker and hopefully with less pain and suffering.
AS ABOVE posts suggest A low aspect foil is way easier to learn on - I personally learnt on a low aspect 2nd hand Spotz 1 free ride head which is super stable and slow which I loved at the time - but also many in Perth have jumped on full racing foils and made it work ( they were already formula kite racers though) - I now ride a high aspect race foil which is crazy fast and needs 90% more concentration to ride but fantastic once you developed the skills necessary.
Personally after foiling for about 1 year and seriously for about 4 months I find that getting into a group of riders and comparing notes after each session is the way to go. Other riders will help you get over the fear of trying new techniques as you progress - Your 1st attempt at a full speed foiling gybe is truly terrifying ...
As you progress fairly quickly to more advanced techniques asking other foilers on the water who are trying to learn or already have mastered them is the best way to go - all of the below will test all of your kiting skills and push your kiting to new levels.
- riding any reach
- blast down wind with speed and control
- down loop kite through turns
- tacking with touch down
- water gybe
- ride toe side
- tack foiling
- foiling gybe
- riding in 25knots
Have fun and see you out there.

P.S - wear an impact vest & helmet
