It's quite difference as your existing racquet. This is the highest level racquet in Wilson, same as Head Prestige Mid, it request player have quite advance skill and complete full swing. It not easy to use. But this racquet not only play in baseline, since the head weight is light, so it will easy to handle volley in the mid court.
Its a great racquet, I have the k90 which has the same mold as the BLX and specs but a bit less vibration reduction. It totally depends on your playing style, if you can generate your own power this racquet will really award you. It will force you to improve your footwork and strokes. Good Luck :]
So far 打左4、5次...
都仲係適應緊，totally agreed with ivancycheng 塊拍係要full swing and vincent_tennis 呢塊拍真係要自己比力，以前網前想放短波唔用力就咁等個波彈番去對方網前arm arm好，而家就要加番d力擋一擋番去..
之前試過k90，個sweet spot應該blx 90 大d，但唔知係咪頭輕尾重關係，感覺上仲要比多d 力個波先去..
I think you can add wegiht to increase control of a 100. You cannot do more with the racq unless you are fed or you are used to a wood racq. Otherwise learn to hit with modern technology. I always beat the guys who uses 90 because they just do not have the strength and skill to use it. Strong advice. Think about it!
