Arcsrule, let me tell you about how I felt when I started in 2013 - simply because it was possible to "fly" on a magic carpet, I wanted to fly not matter what:
All alone, NOBODY in our part of the country (main parts of Denmark) was foiling - but 2 guys had started at the far side of DK so I knew it was possible.
So had to do it trial and error - to see what happened.
Out on days with 5 m2 kites really powered in bigger waves (as these are my usual spots riding with friends), and only very short foiling "rodeo meters" now and then.
After some sessions here and there, one day when the wind was quite stable, and water relatively flat - I could foil for a bit longer, but still super short distances, with lots of concentration, ending in a crash.
When reaching this point, I thought: This is NEVER gonna be possible to do relaxed and easy, no future in this
As nobody else was hydrofoiling, I almost thought: Something must be wrong with my setup, it is not possible that it can be SO sensitive, useless
But I knew there was nothing wrong with the setup, as it was the first kite brand production carbon foil.
Meaning, I had to some extent the same thoughts as you had - "Its not gonna happen"...
Little should I know, that later, I could ride with eyes closed and relaxed both strapless and strapped, and now it has become THE most natural way, riding on the water.
The "light wind advantage" as such, came much later.
So have had the very same thoughts as you had, particularly if you dont ride with others who CAN foil, it is understandable that you can come to a wall of "this does not seem right, its not for me"
Today, where everybody does it, and the windfoilers are coming in huge numbers soon (I am about to also) - it is even worse if you ride alone, because you can see all these videos "how easy it is" - while it is NOT possible for you
So as everybody says - STICK with it, you will never regret and it WILL come to you, just believe in it and take the time it takes - things will turn in a wonderful way
Way better, to talk to, or even ride with others at your local spot, if possible ?
That is how we get new riders into the sport in a few sessions - riding together and giving tips of how to and how not to.
Particularly in onshore winds - body/boarddragging out is impossible even if flat, for almost everyone.
The trick I have found is, to drag just in front of them, so they can see how I hold the board, but most importantly, that it should point HALFWIND and not upwind.
Pointing too high, just like even experienced kitesurfers often do - is the main error when trying to get far out in dead onshore.
And you HAVE to get far out, as you will be dragged downwind the first many days.
This way, they immediately pick up the trick - and boarddrag out just as fast as yourself - incredible and easy now.
When out, we ride close (upwind) look at them and give some pointers what they are doing wrong (IF they are), and what to aim for.
In less than a handfull of sessions, they are suddenly able to ride board down on the water, and go upwind - now it is just a matter of time, as this point is the first major hurdle.
Passing this point, and you are in the clear - and we tell them how "impossible" it will feel, oversensitive and feels impossible to control relaxed, so they know it is not an error - it just takes time.
Many happy new foilers and they get on just fine, with the same slow curve as the rest of us - but with a smile on their face for every little step that succeed
Dont cut your masts/struts - that does not make sense for a good rider like you, only for surfschools with limited time to give a success for the customer.
Makes no sense you dont want to use your LF though ?
Heavy is not a problem at all, and definitely do not make it more difficult thats for sure, and it is not very sharp compared to other foils.
Learn to drag out really far, 100 meter, and learn out there till you run aground and drag out again.
Soon you will be able to ride board flat and keep upwind - and from then, it goes way way faster learning.
Just remember it IS just as difficult and impossible like it feels, yes - but when you find it clicking it will get more and more natural and relaxed so it is worth all the hassle
Keep away from your other boards in the learning period (unless you have a weak mentality) - a classic error that many bring other boards too, and ride these instead, when not succeding on their foil.
Learning muscle memory require you ONLY ride on the foil these days, so the memory isnt confused by different inputs
If you want some self confidence, go out on an other board a different day instead - and enjoy that you CAN still kitesurf, to boost yourself.
But preferably mostly ride your foil in the early learning period if possible.
Later you can easily change boards the very same day back and fourth (but require different kitesizes unless the wind changes a lot), no problem - but dont forget how long it took for you to get confident kitesurfing ?
It is the same full process on a foil, just with the advantage you got the kitehandling nailed.
You dont just "try" to foil - you WANT to foil, and learn, and live life to the fullest learning and advancing and having awesome new experiences of things you would NEVER have thought possible.
