Prism Proton Soft Insanity – 2026 OTB Open – Understable Distance Driver
Float like a butterfly and sting the basket with the 2026 OTB Open Prism Proton Soft Insanity. Featuring a vibrant Marm O. Set design, this special edition takes one of MVP’s most beloved understable distance drivers and pairs it with the premium feel and visual pop of Prism Proton Soft plastic.

Type and Use
The Insanity is a stable‑understable 9‑speed distance driver known for its smooth high‑speed turn and straight‑finishing fade. Often described as a “seasoned Inertia”, it delivers the same workability with less power requirement, making it ideal for players who want worn‑in flight lines straight out of the box.

• Average‑power throwers will experience remarkably straight drives with gentle drift.
• High‑power throwers can shape controlled turnovers, hyzer‑flips, and long, forward‑carrying flights—especially under low ceilings or in tailwinds.

The Insanity shines in backhand drives, but also suits clean, touch‑based forehands and beginner‑power forehand throwers.

Flight Characteristics

• Speed 9 – Controllable distance‑driver speed
• Glide 5 – Smooth carry for extended flights
• Turn -2 – Slow, workable high‑speed turn
• Fade 1.5 – Straight, neutral fade with minimal hook

• Soft, slightly flexible feel for boosted grip
• Stunning translucent Proton core with a radiant Prism rim
• Excellent durability while maintaining a catch‑friendly touch
• Enhanced control on touch shots and angle‑sensitive drives

Recommended For

Fun Fact
The Insanity was designed with softened wing shapes to mimic the true “seasoned driver” experience—right out of the box.

Prism Proton Soft is MVP’s premium plastic blend that combines the translucent clarity of Proton with the striking, durable Prism rim—now paired with a softer, more flexible core for enhanced grip and control. This plastic offers a uniquely comfortable hand feel, increased tackiness, and improved catchability while still maintaining excellent durability.

The soft Proton core provides added touch on approaches and controlled drives, helping the disc sit down more quickly on landing. Meanwhile, the colourful Prism rim not only boosts visual appeal but also increases overall durability around the disc’s edge.

• Soft Proton core for boosted grip and touch control
• Durable Prism rim with vibrant, eye‑catching colour
• Great flexibility for confident releases in all conditions
• High durability despite the softer feel
• Enhanced stopping power—tends to sit where it lands
