I played yesterday with A+70. What an awful shuttle ! It's so heavy, it stays so long in the stringbed, like it was glued, no speed when it comes out from it, even when you hit it hard for smash. Poor sensation, no control at all. It's just probably durable. I will never buy such a bad feeling shuttlecock. No pleasure of play at all.
The last time I checked, the A+70 are a half cut goose feather shuttle which is designed more for the intermediate level players who enjoy some recreational badminton. They are supposedly designed for durability (goose feather) but because of the half cut, they won't perform the same as a full feather shuttlecock like the A+90 and higher. You may enjoy the A+90 more if you're looking for something with better sensation / control / durability. I hope that helps!
This could work well for practice or some intermediate club level badminton. Try taking a look at A+60 [15 / tube] for drills that require multi-shuttle. It may provide you with better value.
We tried different Li Ning shuttles and found out that A+300 hit the sweet spot. They are durable and have nice flight properties. Comparing price on our market with AS40 or even AS30 there is no brainer at the time.
