David Roman Carbon Shaft For play, 12.5mm tip diameter, 21.4mm joint diameter. Radial joint, with joint cap. In my opinion, it's easy to switch from a wooden shaft. The shafts from the three major domestic manufacturers didn't quite suit me, but the David Roman carbon shaft is easy to use. The straightness and spin of carbon are truly impressive. The tip has been replaced with an original tip from our workshop, ready for immediate use. ※This is a completely different player-oriented Chinese-made shaft from the "OK Healing" shaft that is often seen. This time, I am selling a shaft I purchased as a spare. ※I switched from a 314-3. ※This shaft was perfect for me, who was struggling with individual differences in wooden high-tech shafts. The feel is similar to Vantage or a harder Hybrid Alpha, but thanks to the ball release characteristic of carbon, the cue ball doesn't bounce around as much. Long draws don't waver, and follow-through shots are surprisingly sharp without the cue ball jumping, making it fun to play with. I've mainly used Hybrid Alpha, 314-2, and 314-3, but since switching to the David Roman shaft, the product has been so stable that I honestly have lost interest in wooden shafts. (I've tried four David Roman shafts) There is little of the sideways deviation that is common with carbon shafts, making it easy to use. However, because it has power and spin, it can be difficult to control the impact point at first, but once you get used to it, you can hit a wide variety of shots. This is just my personal opinion, but frankly, I think it's silly to buy expensive carbon shafts from the three major domestic manufacturers. It has fewer quirks than the later, lower-priced "Rhino." ※Additional note: Unlike "just a carbon stick" like OK Healing, it also flexes, making it one of the best in terms of cost performance.
