Double Dip: Armstrong Alloy system & S1 Foil
Tested: Alloy mast and fuselage, S1 1250
Pros
- Alloy system fully compatible with Armstrong's carbon wings and tails
- No corrosion after three months of hard use
- S1 is exceptionally easy: forgives big weight errors, soft stall, sinks rather than slaps on landing
- S1 stays composed at the top end
Cons
- S1 is a learner wing by design, with low aspect to avoid tip breaches
Verdict: Perhaps the most accessible foil on the market, on a well-thought-out budget mast.

Armstrong Foils Alloy System 72cm & 85cm 2024
Tested: Alloy mast 72cm and 85cm
Pros
- Surprisingly close to Armstrong's carbon masts
- Solid, wobble-free fit and Armstrong build quality
- Much cheaper entry into the Armstrong system; 2.9 kg at 72 cm
Cons
- A little extra weight and flex felt when pump foiling (about 5% efficiency by the tester's estimate)
Verdict: A no-brainer if price has kept you off Armstrong.
