The Studio B SB10 MR2 is called a "masterpiece among masterpieces" because it comes from Bettinardi's golden era custom line, highly sought after by enthusiasts. It stands apart from the generally available series. Here's why: 1. Special Origin: "Studio B" Studio B is the name of the custom line, located in Bettinardi's Chicago headquarters, where fittings and production are done for professionals and high-end customers. It's not a mass-produced item; each one is made with extreme precision. 2. Rarity of "MR2 (Micro-Resonance 2)" * Unique Sound Design: Designed to produce a "pleasant high-frequency resonance" at impact by creating a cavity (chamber) on the back of the face and adding slits. * Distance Feedback: A very luxurious structure that met the demands of tour professionals at the time, allowing them to "hit distance by sound." 3. Material and Finish Texture The SB10 MR2 uses the finest soft steel (carbon core) and early high-quality stainless steel, exuding a unique aura of a rough yet precise professional tool. It's a very niche item, known only to a select few among golf fans. It will surely become a valuable treasure in the future. ☀︎ This is Bettinardi's "F.I.T. Face (Feel Impact Technology)." The F.I.T. Face is a method of carving deep grooves into the face using Bettinardi's unique "milling (cutting) technology." The F.I.T. Face reduces the contact area between the ball and the metal by approximately 55% by carving deep grooves. This creates an extremely soft feel at impact, as if an insert is present. * Sound: A calm, low sound with suppressed high frequencies. * Touch: Delicate feedback, as if you can feel the distance in the palm of your hand. * Finish: Often a calm black finish (blackening, etc.), a professional-preferred specification that suppresses light reflection at address.
