Have any of you tried these birds, if you have what are your reviews of them? I have only tried the 600& 300
600's & 300's - Great game shuttles with consistent flight (If steamed right and no miss hits). If I had the money I would definitely invest on the 600's 100's, 90's, 80's - If you're on a budget these shuttles will do fine in games. 60's & 40's - I had a tube of 60's and I HATED them with a passion (Training only). Flight of the bird is SUPER SLOW and even if I tip them inwards it's still SLOW after a couple hits :/ 40's are good for training just please don't use them for games lol. And if you mishit, well, what do you expect for $12/tube
A300 is great. Really really durable and consistent flight for a long time. A90 is not worth the money, break and slows down very fast.
A+600 is really nice, being internationally (bwf) approved it's one of the permitted shuttles for tournaments/leagues in our area (Yonex Tournament, Yonex New Official and Victor Master Ace being the others)^^
