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. ※This is a player-oriented Chinese-made shaft, completely different from the "OK Healing" shaft that is often seen. This is an item I purchased as a spare. It will be shipped in its original box. ※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 carbon's characteristic ball release, the cue ball doesn't bounce around. Long draws don't waver, and follow-through shots are surprisingly sharp without the cue ball jumping. 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've honestly lost interest in wooden shafts. (I've tried four David Roman shafts) There's little of the sideways deviation often found with carbon shafts, making it easy to use. However, because it has power and spin, it's 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, it makes me feel like buying expensive carbon shafts from the three major domestic manufacturers is a waste of money. It has fewer quirks than the later-released, lower-priced "Rhino." If you can use the original tip, you can draw the ball with surprising ease. Pushing is also good (doesn't crack). I use a tip with a fast ball release to my liking. ※Additional note: Unlike "just a carbon rod" like OK Healing, it also flexes, making it one of the best in terms of cost performance.
