Hi, guys! I just got an idea that since we have training heavy rackets we should also have heavy shuttlecocks. Do they exist? it should be just a shuttlecock of about 10grams, intentionally slowed down, so it is possible to play with. Training effect should be based on the fact that it is much harder to go through the heavier shuttle. Does it make any sense? Thank you!
Try lining A+70, it's not 10 grams, but it's heavy and slow. Hybrid birdies are slow too when you smash. Usually long rallies with those shuttles.
Now I think there is some sense in training with lightweight shuttlecocks. You learn to go through 3g shuttlecock (which is much easier than through 5g) and then gradually increase weight. For extra power you could go with slightly heavier shuttlcocks as well.
It's not all about the weight, but the way the shuttle absorb the impact and the way it is deformed during it. I absolutely agree with you if you just test by increasing the weight to a good quality birdie. Good quality birdies will for sure be faster the heavier they are. And therefore less good for training reflexes, like you said. But some bad heavy birdies exit the racquet with less speed than lighter good birdies. They are bad for tournament but they could have some interest for specific training purposes.
