Who should throw the Roto Grip Perfect Gem? Throw the Perfect Gem if you have moderate to high revs and need a strong ball that gets through the heads cleaner than the original Gem on medium-heavy to heavy oil. Skip it on a typical medium house shot, or if you're a two-hander on standard patterns.
The best women's bowling shoes are the pair that matches how often you bowl and how your foot is shaped. Start with a fixed-sole athletic shoe if you are leaving rentals, a DexLite Pro BOA or Lady Jet for weekly league, and an SST 8 or THE 9 if the approach changes from house to house.
Choosing the right spare ball comes down to your style, your goals, and the conditions you bowl on. Plastic remains the most reliable option for straight‑line spare shooting, while Viz‑A‑Balls and Clear balls offer personality and premium aesthetics. Plastic balls with cores provide a middle ground, and urethane or reactive options can work for bowlers who want durability beyond traditional plastic options.
