Any one tried these Mizuno shuttlecocks?

Was browsing the net and came across these shuttlecocks - has anyone tried them before? And if so, any feedback, especially for the MS-70 and MS-90?

Sun Power

Found this old shuttlecock in a hall I frequent.

Not used before and has all the hallmarks of a budget product.

Chao Pai Red

Just realised I did not add the review of the Chao Pai Red shuttlecocks to the blog - always thought I had😕

From distributor

When we used the shuttlecock in the past, we found the flight characteristic(s) to be superb and provides very nice feedback upon contact.

Unfortunately, the Chao Pai Red is not durable enough for a heavy smashing game (otherwise ok) - we used up a tube in less than 30mins vs 1hr for our defecto standard. I bought 5-tubes for our initial test and ended up selling the remaining 4-tubes to the group in the next court - they loved it.

The Chao Pai Red is not cheap as it is one of their better products. 

Hence the Chao Pai Red is more suitable for games with non-heavy smashers as it provides much better value than the more establish brands eg RSL Classic Tourney.which has a durability issue as well.
