Editor's take

Yonex 2nd Generation Astrox 99 Pro — stiff shaft (HM Graphite + 2G-Namd FLEX FORCE + Ultra PE Fiber), most head-heavy frame in the current Astrox lineup. 4U avg 83g / 3U avg 86g; recommended tension 4U 20-28 lb, 3U 21-29 lb. Singles attack profile; rewards clean rear-court contact and is unforgiving on late timing.

  BadmintonCN: Astrox 99 Pro 2 firsthand review (May 2022)

  4U/G5 strung 96g w/ heat-shrink, balance 299mm. NAMD shaft 210mm. Box-frame, e.cap, 5-7 line slot. 68-hole stringbed (denser than usual 76; reviewer notes this raises perceived hardness, contrary to the conventional density-equals-softness rule). Frame is small. Hard. Low forgiveness. Headweight feels even heavier than balance number suggests due to handle weighting. Reward when clean; punishment when not. Reviewer reports difficulty driving it in fast doubles — recommends saving for singles or mixed where retrieval pace is lower.
