My brother's girl bought this shuttles for me for Christmas last year and i haven't used them till just recently. I like my Yang Yang 300b and Yonex shuttles. However, those of you who are familiar with this type of shuttle, could you please give me some feedback and opinion. Thanx.... those of you in Singapore, they are available at Sportslink and come in a blue and white tube. Cheaper than the Yonex shuttles but more ragged..... Mines is FS 1135
