Thanks all for the suggestions and ideas!
My weight has been a problem also here, at the local spot, when I asked suggestions regarding equipment: with riders averaging 75kg, people kept suggesting me 138cm boards and 10/11m kites
unfortunately, weighing an extra 30kg does exact (many) a toll, so need adequate equipment.
The spot I have easy access to is rather shallow: it quickly gets to 1m, 1.2m, then there's a "shallow barrier", then it gets deeper (but reasonably so, like 3/5m for quite a distance).
I wonder what a good mast size is for this.
I can body drag easily enough, although I still "need" to look at the kite: as I always practiced in low wind, oftentimes the kite would want to fall down in lulls, or just get its lines rather slack, so having an eye on it helped me correct issues before they became fatal (kite falling in the water).
Perhaps in stronger, steadier winds I might be able to keep it up no-look.
Still, kite fell only the first 2 days; no falls since.
I will check the Clearwater foils (they sure look nice), but I'm most probably going for a complete package.
I'll probably jump on the first deal that comes across, so I won't lose too much on the experiment – plus, I'm a bit scared now of razor sharp Moses, after your suggestions).
(btw: anyone with experience on 2018 Naish Thrust foils? 1 has just popped up...).
The idea of buying a surf to test and sacrifice is probably nice too; but then, I know even less than foils about that (haven't the faintest idea about size for me; my research has been all on twin tips and hydrofoils).
Unfortunately, no one does hydrofoiling here; sometimes kiters come from other spots, but I have counted 3 or 4 hydrofoilers in 60+ total kiters during nice windy days.
Not truly a lot I could ask suggestions to (and would have to wait the next good, windy day, where it's lulling in other spots so they come).
A spot with nice tutoring is 120km from here, one way.
So, am between a foil, and a hard place
Again, thanks all for the helping comments: I'm really excited, and trying to digest all your suggestions.
