Play with the premium golf ball models from this brand with this mix. Each model was designed to fit your game style and deliver high performance in all factors that matter. The Tour B X and Tour B XS models are meant for players with a high swing speed (over 105 mph), and Tour B RX and B RXS are meant for players with a slower swing speed. If there's an "R" in the name, it's for slower swings. Meanwhile, models with "S" in their name are meant to have a higher short game spin. So if you are looking for an extra distance from the tee, the Tour B X and Tour B RX are the better choice. If you are looking for more spin in the green, you should pick the Tour B XS or the Tour B RXS. What can you expect from this mix? Expect a mix of used golf balls that look almost new with Golf Ball Country's 5A/Mint quality golf balls. You'll have the advantage of playing with one of the best golf balls in the world while paying much less for it.
