- Attention Sign

First Impressions
The Roto Grip Attention Sign hit the market in December 2025 and presents itself as a striking, high-powered addition to the asymmetric high-performance segment. Visually, the ball stands out with a very dynamic color combination of Blood Red, White and Black that gives it a strong presence on the lane. The real strength of this model, however, lies in its technological architecture. At its heart sits the innovative Momentous AV + A.I. Core. At the standard 15-pound weight, this asymmetric weight block delivers a low 2.48 RG, a substantial 0.049 differential and a 0.017 mass bias. These particular core numbers point to extremely quick, early rotation paired with very high flare potential. The core is wrapped in the U-R1 Solid Reactive cover, a material developed specifically for maximum traction in oil. The surface comes sanded with a 2000-grit Abralon pad from the factory. The interplay of the heavy-rolling asymmetric core, the firm solid cover and the rough surface should make the ball read through the oil very early. That generates exceptionally stable and even traction in the heads and midlane before the ball makes its angular, powerful change of direction in the back third of the lane.
Comparison Placing it within the internal Roto Grip hierarchy invites a direct comparison with the Roto Grip Attention Star. Where the Attention Star, with its pearl cover, is designed primarily for more length through the heads and a noticeably sharper, snappier change of direction off the backend, the matte U-R1 Solid surface of the Attention Sign produces a much earlier hook. The result is a far smoother, more controlled motion through the midlane that clearly reduces the risk of overreaction. Bringing in the Storm Phaze II as a popular benchmark ball, the Attention Sign shows a substantially more defined and asymmetrically stronger change of direction at the breakpoint thanks to its Momentous AV + A.I. Core. The Phaze II, being a symmetric ball, tends more toward a continuous, rounder arcing reaction. Compared with the 900 Global Reality, the Attention Sign often behaves somewhat cleaner and more free through the front half of the lane. The Reality offers still more overall traction and can hook up early when there is less oil, while the Attention Sign conserves its energy a bit more efficiently to make the final move into the pocket with plenty of hitting power.
On the Lanes The Roto Grip Attention Sign is exceptionally well suited to medium to heavy oil volumes and shows its full range on fresh patterns. Thanks to the tacky 2000-grit surface and the strong, early-rolling core, the ball navigates deep oil in the heads effortlessly without losing meaningful rotational energy. If you have lower ball speed or a lower rev rate in particular, you'll benefit enormously from the core's inherent strength. The ball generates enough traction on its own to develop a stable, powerful hook even when the release isn't optimal. At the same time, if you have a very high rev rate you'll also find an absolutely dependable option here when heavily oiled, long or very flat sport patterns have to be played and maximum control at the breakpoint is a must. Once the lanes dry up over the course of a tournament and the transition sets in clearly, though, a timely switch to balls with cleaner pearl or hybrid covers should be considered. On dried-up boards the Attention Sign can tend to find friction too early and burn off too much energy before it actually reaches the pocket. As long as there is enough oil on the lane, however, this model is characterized by excellent, forgiving carry and makes sure you hit the pocket consistently and with maximum effect.
