I was wondering why BadmintonCentralTV added an extra 2lbs and not 10% difference for the cross. Also, why only add these 2lbs in the middle cross and not the whole cross unlike the Yonex Pattern.
for most applications, 2lbs and 10% is less than 1lbs difference. i doubt you will feel the difference. also the difference maybe vary due to your stringing machine and your technique. at for why just the middle cross, look up proportional stringing.
