Thanks for the comments!
@Icharus, use the same strokes to paddle upwind in 20 knots. I can't say I enjoy foiling in strong onshore winds due to the paddle out but foiling works surprisingly well in onshore conditions, as the wind helps you get up on the foil and stay up and the bumpy/ lumpy/ crappy surf is still fun on a foil.
@DaHammer, I used the foot hooks for a long time and it's much easier to transition to foot hooks at first. Using the foot hooks, I got used to placing my feet before catching the wave, which we will cover in the next video, this made the transition to straps easy.
I recently started using a longer mast (32") which has some advantages but is also harder to control, so I first used a front foot strap and now also use a back strap, which really helps control the foil, especially in turns. I do find my ankles get sore from foiling with straps, I'm hoping they will get stronger from using footstraps.
For starting out, I don't recommend foot straps due to the higher risk of injury but you should have visual/ tactile foot placements on your board - an arch bar under the back foot and at least a visual marker for your front foot.
