The Theory is an understable midrange from Axiom, rated 4 / 4 / -1.5 / 1 — the turning complement to the Alias, on the same 12 mm rim.
A turn of minus one and a half means it drifts right on a flat release at moderate power, and Axiom describes exactly that: predictable turn with “great drift” before a mild fade. For newer players and shorter arms it is the midrange that flies straight and long instead of hyzering out early. Harder throwers will turn it over on a flat release and should use it for anhyzer lines, tailwind holes and the occasional midrange roller. Infinite’s 31 reviewers average it at 4.6 / 4.6 / -1.8 / 0.8 — more turn and less fade than the rating, so treat it as flippier than the numbers suggest.
It takes the understable midrange slot beneath the Alias, and beneath the MVP Tangent in stability. The limit is the obvious one: it will not hold a headwind and it is not a disc for a hard hyzer line.
PDGA approved on 24 September 2014, the Theory is a little taller than the Alias at 1.9 cm and noticeably softer, with a PDGA flexibility of 6.35 kg against the Alias’s 8.96. Axiom offers no explanation of the name. It is out of production; TryDiscs and Infinite both list it as discontinued.
It shipped in Neutron, Proton and Plasma, all with MVP’s overmold rim. Beadless.
How much the Theory turns and fades depends on how hard it is thrown. These three shapes are drawn from the manufacturer’s numbers, not from measured throws.
Measured by the PDGA when the Theory was certified. Each card names discs that share the number, so you can feel it in the hand.
