This project represents Mark’s take on a competition-ready organic, built to balance performance, comfort, and fun. Coming from the early days of yo-yoing, Mark has always favored organic butterfly shapes. They are comfortable in the hand and enjoyable across a wide range of tricks and styles. With the [Blunder Bus](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont), the goal was to explore what a “competition organic” could be. Many modern competition yo-yos rely on sharp angle changes or aggressive V-shaped catch zones for maximum stability and spin time, but often at the cost of playfulness. The [Blunder Bus](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont) aims to find the happiest possible middle ground. [![Black-FRS-Blunder-Bus](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/f/4/6/f4686ff0ff900d0df1809990cda4ca44d661b732.jpeg)](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont) [![Black-FRS-Blunder-Bus-02](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/d/4/5/d45afce1cf98e48008fce29955f869af11286415.jpeg)](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont)[![Black-FRS-Blunder-Bus-03](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/a/e/7/ae71b12dba436c579138256a47d9fd44cda18e5e.jpeg)](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont) The design process began with the One Drop Gauntlet, one of Mark’s longtime favorites. Using its catch zone profile as a foundation, the shape was refined to hit the target weight and feel. The flat rim element was then introduced with restraint. A thin flat rim was chosen to keep transitions smooth and effortless through technical layers. Weight distribution proved to be the biggest challenge. Early prototypes used a mid-weight bump inspired by the Cascade to increase spin time and stability. While this worked technically, the yo-yo lacked the ability to shift speed and tempo easily. It was powerful, but the fun factor was not quite there. The final breakthrough came with a redesigned cup featuring a flowing wave shape. This adjustment transformed the play feel. The [Blunder Bus](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont) became more dynamic, more responsive to tempo changes, and far more expressive on the string. The result is a yo-yo that feels fun and lively, while still delivering strong stability and long spin times. The [FRS Blunder Bus](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont) closes out the Flat Rim Series with a design that blends comfort, control, and character. A serious performer that never forgets to be fun. > **[FRS Blunder Bus](https://yoyoexpert.com/products/frs-blunder-bus-yoyo-by-markmont)** > > The FRS Blunder Bus is the third and final release in Mark Montgomery’s Flat Rim Series.

I think that is a special edition. No recent Markmont that I have purchased either direct or from a retailer includes these extras. ---
