For most bowlers who own multiple ‘strike’ balls, the temptation often comes to switch balls when your ‘preferred’ strike ball isn’t performing as expected. Many bowlers around the 200 level will make the decision to switch to a different ball when the original ball they are using isn’t ‘working correctly’. Sometimes this can make a difference, but the fact of the matter is, the original ball is probably working fine, but you’re just not lined up correctly on the lane (see Starting Position). However, there are several occasions in which changing balls is entirely appropriate and necessary.
Spare shots – If you’re a 150-180 average bowler and you want to improve your average by 10 pins or more, switching to your spare ball for every spare shot can help you out significantly. If you’ve ever thrown your strike ball at a 10 pin or 7 pin, just to see it hook away at the last second, then you know why you should get a spare ball.
With a spare ball, you can throw your normal shot without dramatically changing your starting position, increasing your speed, or having to keep your wrist straight. (Remember bowling is about repetition!).
Sport shot conditions – The PBA line of sport patterns, the USBC National pattern (which changes every year), and many other patterns out there are very difficult assess in 10 to 15 minutes of warm-ups. If you’re preferred ball just isn’t performing (sliding too far, breaking too soon, or is just generally unpredictable), switching to your secondary or tertiary strike balls may be worth a try. Also, remember that certain balls are designed and drilled for conditions that are oily/dry. If your preferred ball performs better on a reasonably dry house shot, you’ll want to use a ball for heavy oil on a sport shot, such as the Storm Timeless Bowling Ball (40% off right now), or the Hammer Gauntlet, which performs spectacularly well in heavy oil conditions.
Dry lanes – Though not common in most leagues, a lot of tournaments, especially ones where you bowl 5 or more games, will see the oil disappear and dry up. This can often leave you scrambling left to stay in the oil and put you in an uncomfortable angle to throw at. Having a Urethane ball in your arsenal can be quite helpful in a dry lane situation, but switching to any less hooking ball will be helpful. It may sound crazy, but don’t rule out throwing your spare ball for a strike as well.
