i used to play with protech platinum... but recently protech platinum giving unstable quality, durable and speed. so i change to RSL classic, no doubt it gives more stability but then the quality is worst than protech platinum. then i bought yonex aerosensa 40 for a try... but it seems worst than RSL classic, compare durability and speed.... and it seems no speed and strength at all when doing smash....or ? that dozen of yonex is old stock ? any recommendation of others shuttlecock for nice game ? wilson ? li-ning ? sea lion ? RCL ? Thanks and have a good day.
