I would recommend a 633 Monofuse that is shaped like normal or with the strut just a little bit more forward as your previous models, but I would take care to give the "cutted" end a nice hydrodynamic shape by reducing diameter, for example by two planes hitting each other with an sharp angle of around 14° as the strut profile does but not necessarily sharp on the end but well rounded with a radius of about 1-2 mm. So you will achive both a low drag but no extra parts but less parts that may hurt you.
I would not recommend a strut over wing concept for first try:
1. As it just feels additionally to the loose pitch also loose or better to say "different" in yaw and combined roll, which you don't want maybe, especially not for the first year of monofoiling
2. By dismounting the stabi your strut position under the board comes about 3 - 6 cm more foreward anyway, so if additionally putting the strut more about 11 cm more forward over the wing will cause that you need an additional track in your board. (I just have one special customeade board with a so much forward track)
3. With the moses system a strut over wing design could maybe become a bit wide and therefore draggy.
I had today my first try in Wing Monofoiling
(again with the duotone 5 m² Foil wing)
and it was as expected very easy, first 3 starts maybe needed a bit more wind or failt, till I found pressure point, but then everything was the same as my other till now two wing foiling sessions.
Even the jibe nr. 3 was already the first successful. Just foot switching for sure could take quite long to learn without stab, as for that the support of the wing is worse then you are used to have by a kite. After 1/2 hour I started to Jibe, Jibe, Jibe, Jibe in just about 8 m distance like mad and as never done with a kite where even with short lines you can't switch course so quick. It was a real pleasure.
Only drawback this day was a start with my 40 l foil raceboard was not successful, not necessarily impossible, but the moment when I managed to stand on the board pressed under water and with the wing flying over my head there was just to low wind to word the board up to the water surface. So I had to use again the giant around 80 litre old kite raceboard.
Hope to find something significant lighter and jumpable with straps, but in the range of 50-70 litres nearly no big surf foil and also no small SUP foil boards. ... and not jet ready for something customade ... even if the XL Groove Skate (ca. 40 l) of a friend is pretty close to what I am looking for ... maybe ad an XXL Skate to my XS Skate .. to think about ...
Oh and last try was with the XXXXL (old kite race) monofoil board and my 5 m² Peak4 in so little and difficult wind that even the Peak sometimes started to collabse ... unexpected this strange setup worked pretty nice and started with no pull in the loops but also due to the mono was able to turn and react fast enough in some strong gusts.
..also tried the Ozone single skin in comparision, but better not talk about that .. let's say, as this is the wrong topic anyway.
