Bias describes the curved path a bowl takes as it slows. Here is how to use that information when comparing models.
Start with how you play
Before comparing prices, identify your usual discipline, surface and level of experience. That removes many unsuitable options immediately.
Compare the details that change the experience
Published specifications, fit, dimensions, playing characteristics and intended use are more useful than choosing by colour or brand name alone.
Build a shortlist, not a shopping cart
Use product pages and manufacturer information to narrow the field. Then compare sensible alternatives and check current retailer price, availability and delivery terms.
Final check before buying
Specifications and retailer listings can change. Confirm any detail that is important to your decision with the manufacturer or retailer before purchasing.
