I have tried to find good shuttles. It is also nice to test shuttles because Im huge fun of badminton.
There is rumours about shuttles:
Forza Vip, not anymore goose
RSL Classic tourney, not always goose??
Youhe S100 goose and natural cork
Victor Master shuttles goose and corks are different between models Ace to no. 6.
Yehlex premiership grade goose
Actually in webshops they dont tell which feather they are and what kind of cork. Only mentioned premium shuttlecock etc.
