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.

Good to Know Before You Buy
·Control over raw hook: The lower differential means moderate total hook. For maximum board coverage on heavy oil, step up to stronger equipment.
·Ships sanded for traction: The 500 Grit finish is built to grip in oil. Polish it for more length when the volume drops.
·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.
BowlersMart Tips: Where the IQ Tour 78/U Fits in Your Storm Arsenal
Where It Fits in Your Arsenal
In the Storm lineup, the IQ Tour 78/U is your urethane control piece on the benchmark IQ Tour platform. Where the reactive IQ Tour reads the mid-lane and hooks to the pocket, the urethane 78/U reads smoothly and predictably with less total hook, so it shines on shorter patterns and tighter conditions. It pairs naturally below your reactive equipment as the controlled option when the lane demands accuracy over angle.
Surface Adjustments
The 500-grit finish gives the 78/U an earlier, controlled urethane read. Take it lower for even more traction, or smooth it up for a bit more length, depending on the pattern. Have surface changes done at your pro shop for an even, consistent finish.
Coverstock Care
Wipe the Control 78 Urethane cover with an approved ball cleaner after every session. Urethane is durable, but keeping it clean preserves the smooth, predictable read that makes the 78/U such a dependable control piece.
