I ordered some tubes of Chao Pai Red and Purple about 18 months ago. Was very impressed with durability and consistency. My club us now looking to place a bulk order of shuttles. We've been using RSL Classic Tourneys, but their consistency and quality have been suspect of late. Can anyone attest to the current quality of Chao Pai? Any reason to buy the Red? I thought purple was about the same. I also know that past quality may not predict future quality, esp. given current bird flu issues. thanks!
