The Tour B X is Bridgestone's distance-leaning tour ball, built for faster swings (around 105 mph and up) that want low driver spin without sacrificing control around the green. Its REACTIV iQ cover flexes for speed on the tee and grabs on the smash for greenside bite, and it's most famous as the ball Tiger Woods plays. If you swing hard and want a firmer, penetrating tour flight, this is the one.
