Sorry Diego, I have no idea...
I dont think the Takuma and short mast is for me though, also because our waves are not long and with big distance so makes no sense here.
Personally when up in 8-900 cm2 sizes, it works awesome for wind at or below 10 knots and riding waves, really fun - but as soon as the wind starts to pick up, they becomes too slow really fast sometimes, at other times they are great riding with a 6 or 7 m2 kite in 12 knots, as they dont outrun even our slow waves here.
So the Takuma style is most likely not for me for these reasons, but as I havent ridden that type, and others like Gunnar love this type, I am not qualified to answer
I can see Alpine got really high AR wings, but hard to find info about any lower AR bigger sized wave wings ?
So understand your question as should you buy a totally new setup board + foil Takuma style, or ?
If Alpine dont have a big low AR wave wing, it is not that easy...
You could get a low cost full new Alufoil, but it might be hard if used to light good gear like you have now.
A full new good foil + board also an option, the most expensive but good
Or you could also get a Ketosfoil without board, t.ex with the WaveXL wing, as the mast will fit your board with one screw, great.
But relatively costly (worth it though ha haa, my friend just bought one after having tried it)
Here we have had a handful of riders having had high AR wings first, and getting a lower AR freeride wing for fun and waves also, or changed the full foil to a freeride type - the opposite has never happened.
