Recently I'd love to use aerobite @ 25lbs. Its feel good repulsion and nice control for my taste. But, after lockdown, when shuttlecock price going sky rocket everywhere in my country, WE decide to use some others cheaper local brands as alternatives, the quality is similar but the speed is vary from one tube. 30% too fast, 70% accepted even it's slower than the previous one. I feel not comfortable to play with this speed, i tried to lower 1lbs aerobite to 24lbs to compensate this condition, the result, i feel just a bit more repulsive, but i feel not so confident to control (stringbed feel softer) Actually i want more repulsive than 24lbs, but im worries to lose control more (especially when i get the 30% too fast). Should i consider to lower 1 or 2 lbs more. Or just stick @ 24lbs keep try adaptation and play more.
