The Darwinian approach of all the main brands has led to and adopted standard of "Strapless" and "thruster" configurations.
What you really need are 5 fin boxes like Airush used to offer.
At your weight you can easily go 5'4 -5'6 in a conventional shape. Decide what fins style you like best and then choose width, it sounds like you don't want much flatness in the rocker either.
Two recommendations would be to try the new construction slingshot, celero FR 5"6 or the tyrant in a 5'8. The tyrant has a width a hair over 17" and 20l in vol. Thruster only though.
Even better get yourself a demo on an appletree, they do 5 boxes and multiple shapes.
First off, let me make the best argument against what I am going to say further below -
its kitesutlrfing and you CAN ride anything with any flaw, and you can even kite a "blow up doll", so nothing has to be perfect to work.
That said,
One of the reason why 5 fin boxes is not as popular any more is that it CAN limit your bottom shape in order to allow different fin configurations to actually work. Given certain widths, a double concave to "V", single concave to flat, or flat to "V", may significantly favor one fin configuration over another.
Also, the side fin locations for a thruster are not always ideal for them to be in the front location on a quad. So some compromises are made between these locations for the quad vs thruster.
Given the above, sometimes the center fin, or the rear quad fin locations are moved from the ideal location to account for the above also. This means that you have a possibility of both the thruster and quad locations to be in a very compromised location. While this can be fixed to some degree with fin set experimentation, how many shapers or kiters are going to try 6 different sets of fins in each configuration on a board?
So basically when you have 5 fin boxes, the shape is more restricted, while having to deal with many more variables to make a board that works both ways. It's kind of a headache for shapers, but fortunately a kiter can easily make "less than perfect" work.
However, I will side with you in that strapless, and specifically "strapless because it's cool" riders, have heavily influenced the trend toward thruster popularity. If straps were more popular, I would say up to half of the directionals out there would be quads.
