Prototype I is exactly what the name says: an Infinite Discs test mold sold without a finished identity, which makes it a bit of a collector's curiosity. The flight itself is familiar fairway driver territory, slightly stable with a touch of early movement and a moderate, predictable finish. Anyone comfortable at this speed can throw it for controlled drives and gentle flex lines. Just know that prototype runs can vary, so the copy in your hand is the real spec sheet.
