- 505A

First Impressions
With the 505A, Track brings a fascinating new development to market, one that stands out above all for its exceptional length and late reaction. Inside works the dynamic Legion core, which with a 2.50 RG and a 0.046 differential ensures very clean motion through the front sections of the lane. The Gen X A Pearl cover is specifically tuned to store the ball's energy extremely efficiently. The surface, with a Polished finish, massively supports this trait by letting the ball glide effortlessly through the heads without building friction early. Visually the ball is a real eye-catcher and immediately signals that this model was designed primarily for later and sharper direction changes. The technical match between core and cover is extremely harmonious and purposeful here.
Comparison
Comparing the 505A with the Storm Tropical Surge, the glaring differences in backend reaction are immediately apparent. The Storm Tropical Surge tends to read a bit earlier, while the 505A holds its energy a decisive fraction longer and then reacts noticeably more aggressively to the dry area. That trait makes it the perfect complement in your arsenal when the Tropical Surge starts losing energy into the pocket or entering too flat. Although both balls are aimed at lighter oil patterns, the 505A offers a noticeably more dynamic angle. It is the ideal solution for situations in which the Tropical Surge no longer generates enough drive, since it creates the necessary entry angle.
On the Lanes
This ball shows its greatest strength when the lane has already been played in 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 produces maximum, explosive carry. As the boards in the front part of the lane dry up, the ball allows you to move systematically further inside and attack the pocket from a much deeper angle. It works excellently on medium to dry conditions and is an outstanding choice if you're looking for a clean, responsive cover. With its forgiving nature on shots missed to the outside, it should keep your scores stable at a very high level even in the late stages of a tournament.
