This is to owners of these racquets and how they feel about the durability of these racquets Yonex NF800 4U Yonex NF1000z 4U Victor AS 100x 4U Victor BS 12SE 4U I am an intermediate level player who started playing after a long time. I play 2 hours daily for around 5-6 days a week. I focus on front court mainly and sometimes if required have to take care from the back court. Would love to hear about the durability (&comparison if anyone has all) of these racquets. Specifically I am looking for the more durable out of these.
