What separates golf-ball construction and cover choices?

The numbers are maker claims without a stated common measurement basis. They do not establish distance, spin or feel for your swing. Treat the layer and cover choices as construction preferences, and read the exact model’s description. Snell’s MTB Black LTD has 3-piece construction and a cast-urethane cover; PR4 has 4-piece construction and urethane. Their compression figures are maker claims. For a different layer count, PR4 meets that preference. Compression values of 85 and 90 lack a stated shared measurement basis, so small differences cannot predict your results.

The comparison uses the range’s upper endpoint, rather than inventing a single measured value inside it. That convention helps you compare the labels, but small differences between models remain an uncertain basis for a performance decision.
