- Secret Diamond

First Impressions
The Secret Diamond is the newest addition to the Diamond series from Legends/Lane Masters and shows up in its characteristic design. At its heart is the Dynasty ver.2 core with an RG of 2.547 and a differential of 0.058, giving the ball symmetric properties. The cover is the XRT 1321 solid coverstock, sanded to 4000 grit out of the box. The ball was released in September 2021 and is designed for medium to heavy lane conditions.
Comparison
The Secret Diamond pairs the Dynasty core with a solid cover to produce the smooth, predictable ball motion that more demanding oil patterns call for. Compared to other balls in the Diamond series such as the Legends Gold Diamond, which works with a pearl cover and a lower differential, the Secret Diamond offers a more controlled and earlier reaction. Where more aggressive balls like the Storm Phaze II are characterized by higher differentials and more reactive covers, the Secret Diamond goes for predictability and a controlled hook build-up. The 4000 surface positions it between the high-gloss polished pearl versions and the rougher 2000 or 3000 variants from other manufacturers.
On the Lanes
The Secret Diamond should show its strengths above all when precise results are what matter. Its design for medium to heavy oil conditions makes it a dependable option if you need consistent performance on sport patterns or longer house shots. The combination of a moderate RG and a solid cover should allow for even energy transfer into the pins without provoking unpredictable reactions. If you have a medium to higher rev rate, you'll find a partner here for situations where carry matters more than maximum hook. The 4000 surface also allows adjustments through polishing or further dulling as needed, to match the ball to different lane conditions.
