If the hits are HURTING you but not WOUNDING you then Id say that thats probably to your best Interest . You may not even realist it yourself but you correct yourself MUCH faster when the consequences for mistakes are more real . A friend of mine that teaches Okinawan Weapons wont give out Foam nunchaku for that very reason . He says that it takes them a couple of MONTHS with Foam chucks , and a couple of WEEKS with the real thing .
