Sabfoil 679 on Slingshot Phantasm which stabilizer?

[Dkite]

I have the Slingshot Phantasm 633 foil.
Now to upgrade it a little I had bought a Sabfoil 679 frontwing.

It rides decent with the Slingshot PS 400 stabilizer which has the following specs:
SURFACE AREA (cm2) = 281
SPAN (mm) = 400
CHORD (mm) = 88
ASPECT RATIO = 5.9

What would be the best stabilizer for this setup?
And can I mount Sabfoil/Moses stabilizers on the Phantasm Fuselage?

If not the only other alternative is the Slingshot PS 325 stabilizer with the following specs:
SURFACE AREA (cm2) = 212
SPAN (mm) = 325
CHORD (mm) = 76
ASPECT RATIO = 5.3

Here's my setup:

Since Slingshot chose Phantasm stabilizer to be incompatible with Moses/Sabfoil hole spacing it doesn’t leave you with many choices.

I have several friends who’ve been riding 683s/679 with Moses 425 stabilizer (good old one, not the thing they released later). Yet personally I don’t like that combo - I feel it’s lacking stability.

I used to ride mine with 483/450 stabilizers and they worked well. What you have now is similar to 483.

I feel larger kitefoil wings work better with rather large stabilizer. It matters way less for winging application though.

You can take a file and extend Moses stabilizer holes a bit to make them fit Phantasm fuselage, but I can’t think of any Moses stabilizer to recommend. I recommend RDB 310 cm² to folks riding 483/450 but not sure you’d want to deal with stretching the mount holes.

I would personally choose the 325 which is 212 cm2.

Ride a similar frontwing with a 170 cm2 stab myself.

But each to their own regarding stab size, I know.

I decided to order the PS325 (212cm2) stab from Slingshot.
Its on backorder so I wont get it until spring, I'll update this when I get to try it.
