Westside Disc Golf BT Lite Rill Underworld Fairway Driver 7/6/-3/1 - Choose Exact Disc
SKU: DG-WD-BTLR-UND (REF2924-2)
Description
The Westside BT Light Rill Underworld fairway driver is a beginner-friendly, understable fairway driver, molded in BT Light Rill plastic. It's built for newer players and anyone who wants easy distance and turnovers, and it's at its best on anhyzers and rollers. Westside Discs is a Finnish brand known for mythology-inspired mold names, molded at Latitude 64's factory in Sweden as part of the Trilogy family alongside Latitude 64 and Dynamic Discs.
BT Light Rill Plastic
BT Light is a lightweight plastic designed to make every throw feel easier. Its reduced weight helps players generate speed and distance with less effort, while the familiar BT feel gives a comfortable grip, making Westside molds more accessible to beginners, juniors, and anyone looking for an easier throw. Rill is a limited-run effect Westside applies over a plastic you already know, with the same plastic character underneath.
The Mold
Designed with the newer player in mind, the Underworld lets any player hit an anhyzer. It's understable and low profile, a great first disc, and for pros it makes a great continuous anhyzer line and rolls right out of the box.
Stability
The Underworld is understable. Understable discs turn away from your throwing arm at speed, making turnovers and hyzer-flips easier and helping lower-power players fly straight. For right-hand backhand (RHBH) throwers, it tends to drift right during the fastest part of its flight, then shows a gentle fade back to the left. Left-hand backhand (LHBH) throwers will see the mirror image, drifting left early and fading right at the end. Forehand flights flip that pattern: right-hand forehand (RHFH) follows the LHBH line and left-hand forehand (LHFH) follows the RHBH line. It suits beginners who need help getting straight flights as well as advanced players who want to shape turnovers.
Flight Numbers
| Rating | Value | What it means |
|---|---|---|
| Speed | 7 | Fairway speed, manageable for most arms. |
| Glide | 6 | Huge glide that floats a long way with little effort. |
| Turn | -3 | Noticeable turn to the right (RHBH) at speed, great for turnovers and hyzer-flips. |
| Fade | 1 | Very little fade, so it finishes nearly straight. |
