Aaah, okay Flaps, now I get it.
So you want to get a "new platform" where you can get different wings that suits both marginal wind / learning new things, and higher wind and speeds.
Or do you want to keep your Silente ?
It seems that all three options you are aiming for are good ones, as Frank also says - nothing to say against either of them.
So it is up to two or three things, which sizes are the wings available for a system (actually total lift as the size is only one parameter), and which connection systems - and somewhat which available boards ?
Wings, I assume you know what is available and which sizes from the 3 brands.
Connection system - personal preferences as apparently no standard yet, not possible as you lose the option for thinner boards if too deep, plate is bulky and slow, and too small is not as strong for racing so you have to choose what you want.
Boards ? Many choices, ie for the onescrew KFBox there are also Alpine boards: http://www.alpinefoil.com/pages-hydrofo ... oil/board/
and the same goes for others connection systems, there are always some making "big" boards for every system.
No, I dont have the new Ketos FR2 wing.
I have the Racewing, Wavewing, Freeridewing (FR1 you might call it, higher aspect and smaller than FR2), Easywing (L you might call it as smaller than the new XL).
Some, me included on some days, use the really big wing for waveriding, as then you can "hang" onto the waveface fully foiling, maybe using the small rear wing so more agile
My current wings, Easy, Free, Wave, Race/Speed: 800, 595, 570, 523 cm2
Using the 3 left ones the most, and the small one to the right sometimes for big air and strapped freestyle jumping (with a shorter mast), but the wavewing is also excellent for this.
Shot last summer with the big stabilizer (using the small one instead very often now), Wave-Easy-Free-Race:
Could easily live without the smallest wing (but not without the 3 others), but now I got it, it is used occasionally...
Having 4 boards, the Takoon above is my allround board right now, for everything.
I like the KFBox with one screw, not too deep so fits both allround and thinner waveboards too and not bulky, and as I change boards very often (and for packdown when not space in the car) the KFBox is one of the reasons for my choice.
Others like you have different wishes regarding connection preferences.
Your question is valid and difficult as they are all very different - and now you CAN ride, you want a modular system that ticks most of your boxes
Many ways to get to this, the upgrade for the newer hp560 is an easy fix and good compromise too
As you can see, we all like what we use now as you can see, and what some of us have used of some other brands also works great - so it is more a question of you having to make a choice Flaps
