The Armstrong performed flawlessly. I had several long rides picking up the waves from the reform and riding them all the way in to the beach. I could feel the 'mast flex' on the turns - and I'm finding myself repositioning my feet and leaning differently to compensate. This never happened on the Go Foil or the Slingshot (as they are both way stiffer) - but flex is a good thing. I'll just need to figure out how to use this to my advantage.
I also almost lost it on a few waves by touching down, but the foil allowed me to correct the mistakes by pumping out of the bogs and I was able to take off again.
This foil also did not breach - I felt like I was flying the foil just beneath the surface (based on how high I was up in the air) and it never dropped me (cavitation = loss of lift) once. If this pans out to be the case every time, I'll be able to push this thing harder because I won't have to worry about surprise drops.
I tried a few takeoffs on steeper waves and I never felt like I was going to lose it - I just popped up and applied back foot pressure and up went the foil whenever I was ready. I'm still getting used to this - but this to me is more familar - closer to surfing takeoffs.
I'm still planning to do the swaps back and forth with the other foils I have (until they sell on Craigslist), just to keep my riding skills sharp - but the Armstrong CF1600 is a really outstanding wing. It'll be interesting to see if riding the Armstrong changes the way I ride the others...
