The listed price is for the ball only, but drilling services are available for an additional fee. The cost will vary depending on the specific work required, but we will offer it at a price lower than bowling alley rates. We can also accommodate difficult tasks such as IT work if you consult with us in advance. We will discuss the layout with a dedicated driller while you send us your measure sheet, so please feel free to ask any questions you may have. This is a new Storm Trend 2 from High Sports. Please refer to the outer box in the photo for specifications. The following is a quote from High Sports. The "Trend 2" is Storm's most confident creation among all their signature line products released to date. Jason Belmonte says, "With a stronger cover and a redesigned weight block, we've created a monster ball that fits all styles of bowlers." The "Trend 2" allows you to move even deeper inside without losing your entry angle into the pocket. By lowering the density of the [Piston Core], we created the [Piston LD Core] with a higher RG and lower differential. The goal is to increase sustained performance from the end of the pattern. This level of differential creates a consistent motion without locking or quickly standing up the core's motion. The polished [NRG Hybrid] cover helps it glide through the front of the lane and increases grip on the backend. The "Trend 2" should be your choice when you need explosive power on the backend on conditions where the oil has broken down.
