The perks of the previous racket remained - I was able to get a very steep downward stroke, and that added to the variety of shots that I had for my game. Being that much lighter (I reckon about 5g or so) I was also able to turn the racket around faster for the defensive shots.
The smashes also came off quick with the silver version of the Li-Ning Air-Stream N55-III, thanks partly to the Air-Stream system that reduces drag around the racket head. The swings don't come off sounding like they're powerful, but when you contact the shuttle it's another matter.
But what really surprised me today was the amount of power that I had with this racket on the backhand. I managed to put a shuttle out of the court from a backcourt backhand clear. I usually add a little more strength when I do a clear, but with this racket I could feel that I didn't need as much.
Will have to experiment more to find out. For now, the silver version seems to work out better for me.
