- Retro RG Spare

First Impressions
With the Retro RG Spare, Roto Grip brings a fascinating new development to market that stands out above all for its exceptional length and late reaction. Inside works the dynamic Pancake core, which with a 2.69 RG and a 0.019 differential ensures a very clean motion through the front part of the lane. The polyester cover is specifically tuned to store the ball's energy extremely efficiently. The surface, with a Polished finish, supports this characteristic in a big way by letting the ball glide effortlessly through the heads without building friction early. Visually it's a real eye-catcher and immediately communicates that this model was designed primarily for later, sharper direction changes. The technical match between core and cover is extremely harmonious and purposeful here.
Comparison
Comparing the Retro RG Spare with the Ebonite Maxim, the glaring differences in backend reaction stand out immediately. The Ebonite Maxim tends to read a bit earlier, while the Retro RG Spare holds its energy a decisive fraction longer and then responds noticeably more aggressively to the dry area. That characteristic makes it the perfect complement in your arsenal when the Maxim starts losing energy in the pocket or entering too flat. Although both balls are aimed at lighter oil patterns, this ball offers a noticeably more dynamic angle. It's the ideal solution for situations in which the Maxim no longer develops enough drive, because it generates the necessary entry angle.
On the Lanes
This ball shows its greatest strength once the lane has already broken down a bit and the transition has clearly set in. It needs a certain amount of friction in the backend to develop its characteristic hook, which delivers maximum, explosive carry. As the boards in the front part of the lane dry up, it allows you to systematically move further inside and attack the pocket from a much deeper angle. It works excellently on medium to dry conditions and is an excellent choice if you're looking for a clean, quick-responding surface. Thanks to its forgiving nature on misses out, it should keep scores stable at a very high level even in the late stages of a tournament.
