The Kastaplast Idog is a 7-speed stable fairway driver. With published flight numbers of 7 / 5 / -0.5 / 2, it is most often described as suited for flat tee shots down a tight fairway, sidearm approaches that need a predictable finish.

Overview

The Kastaplast Idog is a 7/5/-0.5/2 fairway driver that Kastaplast sells as a control disc: “To control the fairway is to control the game and Idog is the new fairway driver in charge of this task.”[1] The company describes a flight that holds a flat line “with a gentle flip” before a dependable fade, and recommends the mold for intermediate and advanced players.[1] The PDGA records it at 21.2 cm diameter, 1.8 cm height, 1.1 cm rim depth and a 1.8 cm rim, with a 176.0 g maximum weight — a shallow, narrow-plate profile that reads faster in the hand than its 7 speed suggests.[2]

Flight numbers describe the published behavior of the disc when thrown at its design speed. Real-world flight varies with plastic, weight, age, and thrower power. The community-averaged numbers above reflect crowd-sourced observations from real throws — typically slightly more understable than the manufacturer's published values, which is the most consistent pattern across nearly every commercial mold.

Kastaplast’s own shot list is unusually concrete: “Send it flat and watch it hold the line with a gentle flip, use it for tricky sidearm approaches, throw it high and trust the fade.”[1] That covers the three jobs the disc is built for — straight controlled tee shots on tight fairways, forehand approaches that need a reliable finish, and high hyzer lines where the half-step of turn keeps the disc from stalling early. Kastaplast stocks the Idog in 170–172 g and 173 g-plus brackets only.[1]

Best for:

  • Flat tee shots down a tight fairway
  • Sidearm approaches that need a predictable finish
  • High hyzer lines that trust the fade
  • Controlled placement drives inside distance-driver range

Plastics & variants

The Idog is available in the following plastic blends from Kastaplast:[1]

K1, K1 Glow, K1 Grind

Plastic blend significantly affects flight character. Premium plastics like Champion, Z, or C-Line generally fly more overstable when fresh and hold their stability over time. Base plastics like DX, Pro, or Active beat in faster and become more understable workhorses with use.

History

The PDGA approved the Idog on 22 April 2024 under certification number 24-87.[2] Kastaplast’s news blog carries no launch post for the mold, so there is no manufacturer-stated retail date; a first-run K1 batch did ship, and the store still lists a K1 Idog First Run X-out from it.[3] The name is Kastaplast’s own gloss: “Idog is an old uncommon Swedish word for diligence or industrious, and this is what we want it to become, a reliable workhorse a new best friend.”[1] Stock plastic is K1, joined by the recycled K1 Grind and a K1 Glow run.[1][5] A K1 Hard Idog exists only as Jesse Nieminen’s 2026 Tour Series release rather than as a stock option.[4] A tour-series stamp is not evidence that a player bags a mold, so no notable throwers are claimed here, and no designer is credited on any Kastaplast page. Independent coverage remains thin: Disc Golf Puttheads has no Idog entry, so the sourcing below is the PDGA record plus Kastaplast’s own pages.[2]
