Hi everyone, Lately i've been using nylon shuttlecocks due to my low budget. But, recently i've had the urge to start playing with actual feathered buts and I came across these shuttlecocks with a very attracting price. I was looking at the model BS01, ST02 and the "tournament premium A". If anyone could give me any feedback on them it would be great! Thank you every! =) P.S: go to open tip.com and then under category sporting goods search "shuttlecock"
