For winter, the HEAD TOUR is the perfect ball. Especially in temperatures below 10oC, where other balls can't even be lifted with a crane, this one has the desired bounce and lasts a long time.

For summer, it will only give you a hard time during the first hour of play due to its extremely high bounce. However, afterwards, it maintains a proper bounce for a long period of time.

Of course, for summer or clay courts, I would also recommend their "siblings," the HEAD TOUR XT, which are more suitable for these cases.

Overall, I would say it is among the top 3 competitive balls with a great quality-price ratio.
