Been riding the Armstrong for over a month now so time to share how it goes. Bit of context - I am an average foiler, been doing it for about 6 to 8 months now, my previous foil was an Axis and I weigh 105 kegs.
What is not to like about the construction and finish of the Armstrong. All first-rate and it comes in a neat bag with padded bags for all the bits.

The bolts holding the one-piece mast on to the board were a bit short so I got some longer ones from bunnings for $5. Titanium plates are nice but a bit fiddley fitting them.

6 screws hold the whole thing together, 2 for the front wing, 2 for the fuse to mast and 2 for the rear wing. Really neat locking system for the front wing and fuse all constructed of carbon and titanium so no corrosion issues.

Fits neatly in the car. No need to pull apart and clean all the time. No fizz bro

The 1600 wing feels about the same as an 82 Axis wing for lift. The set up is noticeably lighter than the Axis, with a bit of flex in the mast compared to the super stiff Axis mast. I feel slightly less stable on the board as the foil reacts to currents underwater more rapidly. Probably due to the lower weight of the foil and the fact that it possibly floats (have not tested it yet).
Feels really reactive on the wave and generates huge speed through turns with the flex helping there I think. To see what is possible go to

Really happy with the foil, it feels more back foot surfy than the Axis, which I always felt was really front foot pressure all the time. The Armstrong likes to be turned and pumped to keep up to speed whereas the Axis was happy to keep going with less input.
The best thing is no bloody Tefgel
Only negative is the price
