Have you considered a strapped waveboard ?
Or does it have to be strapless, and if, why ???
Would just point out, that you can really have a lot of fun on a waveboard in itsy titsy tiny small waves too.
The reason for me saying this is, that I do both - but can definitely recommend straps when it gets small and choppy especially.
Because - if you dont have any religous thoughs regarding straps or not, then you can ride and spray the small waves better (but can be done on both, true).
But especially when the wind and waves are in the same direction, it is better to "smack" with straps - whereas more sideshore it is the same.
And you can make aerial transitions a lot higher and cleaner, kiteloops, super high jumps etc etc.
Besides that, your upwind abitily will be better, and you can (if you prefer sometimes) also ride much faster in chop because you have the board fixed much better, instead of just "plowing" through - it actually rides across the chop faster and efficient
Jibes and Tacks are of course a bit more difficult with straps - but take this as a good challenge and you will be a better kitesurfer
Here, out yesterday locally with no waves almost, and slashing a 1 foot ancle snapper, just for fun and beatiful sun :
This can never be wave "riding", but can be really fun.
Of course, if you have never surfed at all - I would advice to start strapless to learn to use the edges and how it works, and then you can proceed with straps later if you want.
Just another idea instead of going on the "wagon" like most
