The Biome is a putt and approach disc rated 3/4/-1/0.5. A turn rating of -1 with a light fade suggests a straight, gliding putter flight; on throws with enough speed, some right drift for a right-hand backhand, then a soft finish. Its ratings suggest it is less suited to players seeking a strong fade on approaches. Rogue Iron Disc Golf calls it a straight-flying putter with some glide for longer putts and throws, and offers it in its Ecotope plastic, which it pitches for grip and which TryDiscs does not yet record. The PDGA approved it on 2 October 2023 (23-226). Rogue Iron says the proceeds from the first 100 discs of each launch go to Second Chance Farm in Granbury. TryDiscs does not yet record a plastic row for it as of September 2026.
