Goat Darts
The Sprocket is the range to look at for spread — seven weights from 21g to 32g across two barrel lengths, with the heavier ones moving to 53mm so the diameter stays sensible rather than climbing past 8mm.
Grip ratings cover the full scale here. The Quarterback sits at 1 out of 5, about as smooth as a cut barrel gets, with the bomb profile doing all the holding instead. The Podium ring cuts run at 3.5, the firmest in the range.
The 80% barrels use length to stay slim — the Surfer holds 6.3mm at 20g on a 53mm shaft, which is narrower than plenty of 90% barrels at the same weight. The 90% ranges cover the Fairway, Quarterback and Traction.
