Yetao最近喜欢上打乒乓球，开始用正胶，可能是觉得击打比较舒服，后来看我和本的反胶球拍击球威力很大，就也想换个反胶。我手头只有一块 Hadraw SK 贴着快两年旧的 Tenergy 05-FX，拍子有点重，而且胶皮也老了，就给她换了一个 Joola X-Plode Sensitive，也是以击打为主。粘的时候旧板子除胶可真是费了一番功夫！ 拍子粘好了： Hadraw SK + 2 * X-Plode Sensitive = 182 克 我的拍子：Timo Boll ZLF + 2 * Evolution MX-S （软胶面，硬海绵）= 192 克 Ben的拍子：Timo Boll Allround + 2 * Sapphira = 161 克 看来Ben的拍子还是最轻呀。
