⚖️ Choosing Weight
- A common starting point is roughly 10% of body weight, adjusted for comfort and injury history — not a hard rule
- You should be able to swing smoothly without muscling the ball
- Youth and rehab situations often need lighter weights — when unsure, ask a coach or pro shop

📐 Reading Specs
- Coverstock: plastic/polyester (control), urethane, reactive resin (more hook potential)
- RG / Differential / Intermediate Diff: describe core shape and flair potential — useful once you match balls to conditions
- Surface grit: factory finish affects length and backend; you can re-surface later

🟣 Urethane & Rule Changes
Urethane equipment remains popular; tournament rules can limit certain urethane use. See our current note: USBC Urethane Ball Rules 2026.
↩️ Returns & Defects
- Undrilled unused balls: eligible under the 60-day return window
- Drilled balls: not returnable; manufacturing defects still go through defect claims
- Air bubbles, pinholes, and cosmetic pour marks are often normal manufacturing characteristics — see defect guide
