These days almost all driver heads are made of Titanium alloy (钛合金) while shaft can be either steel or graphite (碳纤维). The difference typically lies in the specific quality (type, grade and supplier) of steel, 钛合金 and 碳纤维 used and the way how they are put together to make the club (i.e. club design). Callaway is simply a more regignized name in golf and many of us use its clubs (other recognized names include Talyormade, Titlelist, Ping, Mizuno, Nike, Cleveland, Adams and Cobra etc - check Golftown.com).
钢杆身与碳素杆身的选择,基本上可以说钢杆身打得更准,碳素杆身打得更远。这就是为什么顶级职业选手几乎全用钢杆身,老年选手多用碳素杆身。碳素杆身的球杆每套比同型号的钢杆身球杆大约贵15%左右,比如Mizuno JPX-825 Mens Iron Sets Graphite $899.99, Steel $699.99。孩子初学,既长身体,又培养球性,建议买钢杆身。不过小于10岁就无所谓了。 四、五十岁的初学者,碳素的比较好。
