From Duncan:Working on the GTR, we took strong design notes from the Grasshopper GTX, but certainly weren’t afraid to stray from that path. Our goal wasn’t to make a replacement for the well-received and much-loved Grasshopper GTX design—we think everyone is satisfied with that design as-is. Instead, we sought to create a unique design that compliments the Grasshopper GTX. We like to think the GTR is to the Grasshopper GTX what ice cream is to milkshakes: Similar, but individually delicious for unique and distinguishable reasons. The design process itself was intricate and full of small subtleties that made big changes. Working on a bimetal design always entails hours of tuning the body and focusing on the stainless steel ring to optimize both durability and playability, and this time was no exception: We spent a lot of our time honing in on this design. This yo-yo will be joining the ranks of our more premium yo-yos, such as what can be found in our GTX / X series of yo-yos, but we feel this design is a step up from this already-successful series, and we think you will agree.
