Yonex Aeroclear

I noticed some sellers selling a new shuttle Yonex Aeroclear 30 at a cheaper price than the Aerosensa range. They look to be goose feathers but only B grade it terms of durability.

Strangely, not much fanfare or news from the Yonex website. I guess these are just trying to capture the mid- lower end of the market?

Anyone tried them yet?
