I've been playing since the start of this year I think, and the racquet I'm using is the Yonex Armotec 700. I switched over to badminton from tennis mainly because I couldn't find my coach anymore It's a pretty fun sport, one that's easy to pick up, but a little harder to master.

I was flicking through my froogle search and found this:

E-4431 Training High Quality Feather Shuttlecocks

Anyone play badminton can help me to make a judge of those Shuttlecocks?

If they can last longer in training or advance I think it is pretty good deal(bascially $0.8 per shuttlecock) compared to other brand at it's price.

but as I've never played with them before I have no idea of their performance, does anyone have any experience with these shuttles at all? Any help would be appreciated, thanks!

I try to play once every week, ive been playing for years now. I havent played too much with feather shuttlecocks, not even in tournaments, moreso with plastic ones. I havent a clue what make my racket is, but i suspect that it is a carlton raquet, as stated on the case . . .

I do, though I kind've stink at it.
