Okay, I think I have enough of experience on these shuttles. They are:
Yonex AS20
Yonex AS30
Yonex AS40
Yonex AS50
and here is my little review
-----------------------------------------
Performance:
AS50 is about the same as AS40, and I can't really tell which one is which if you mix them. Also, the flight of AS40 and 50 is about the same. Good Quality.
AS20 is ok, but sometimes feels a little sloopy. AS30 is a little better, but not too far from AS20.
------------------------------------------
Durability:
I think AS40 last the most. It can last about 2 games if you hit it well. AS50 is little shorter than AS40, but it's generally above average.
AS20 and AS30 are the same, last only 1 game, or sometimes 10 points. I wouldn't say AS30 is better than AS20 in this area because it isn't.
-------------------------------------------
Price(in Taiwan, and used 1:33 as the rate to the US dollars.):
AS50: $13~$14
AS40: $12~$13
AS30: $11~$12
AS20: $10~$11
and I think I will only buy AS20 and AS40 since I think they have better values.
Use AS20 for regular play and use AS40 for games with people.
The price in the US is very high, I know. However, in TW, they are not as expensive though
