Storm IQ Tour 78/U Bowling Ball

The Benchmark Core in a Control Urethane

About the IQ Tour 78/U

If you are looking for a smooth and predictable reaction, the Storm IQ Tour 78/U may be exactly what you need. Storm took the legendary IQ Tour core and paired it with a new urethane material, creating a control piece that combines the workability of a benchmark ball with the predictable, lower-hook motion of urethane.

The IQ Tour 78/U pairs the symmetric C3 Centripetal Control Core, the same proven engine as the original IQ Tour, with the Control 78 Solid Urethane coverstock at a 500-grit finish. The 78-hardness urethane reads the lane gently and predictably, giving you a smooth, controllable shape on shorter patterns and drier conditions where a reactive ball would over-hook.

Understanding the Storm C3 Centripetal Control Core and Storm Control 78 Solid Urethane

Storm built the IQ Tour 78/U for control. Specifically, the symmetric C3 Centripetal Control Core revs up quickly with a smooth change of direction, while the Control 78 Solid Urethane cover at a 500-grit finish reads the lane gently rather than snapping like reactive resin. As a result, it delivers the workable, forgiving motion of the IQ Tour core with the predictable, lower-hook reaction of urethane, ideal for shorter patterns and tighter conditions. The full per-weight specifications are listed below.

The Benchmark IQ Tour Core, Built for Workability and Control

At the heart of the IQ Tour 78/U is the symmetric C3 Centripetal Control Core, the same engine that made the original IQ Tour a benchmark. At 15 lb it measures RG 2.49 and a .029 differential, numbers that produce a smooth, controllable motion. The core revs up quickly and provides a smoother change of direction down-lane, with a low center of gravity that gives players control at the breakpoint.

On the 78/U, that workable core is paired with a urethane cover, so its forgiving motion comes with even more control. As a symmetric core, it reads the lane predictably and repeats the same shape shot after shot, the proven IQ Tour read, now in a lower-hook urethane package.

A 78-Hardness Urethane Cover for Smooth, Predictable Control

The IQ Tour 78/U wraps that core in the Control 78 Solid Urethane coverstock at a 500-grit finish. Urethane is a milder material than reactive resin: it grips the lane gently and reads smoothly, so the 78/U holds a controlled line instead of snapping at the breakpoint. The 500-grit sanded surface gives it an earlier, even read for traction on shorter patterns.

That controlled urethane motion is exactly what makes the 78/U so useful when conditions get tight. On shorter oil patterns and drier lanes, it gives you a smooth, predictable shape where a reactive ball would jump or over-hook. Adjust the surface at your pro shop to fine-tune the read, lower grit for more traction, higher for a touch more length.
