He trained in Shukokai and my son is doing Shokotan, it wasn't something he has volunteered for they have really played the emotional blackmail card - your son will only be able to grade every 6m rather than 3m unless you help run a second class. He has been told he will be able to take the black belt in Shokotan if he produces his license and he wont be running the class alone. He's kept really fit and has been competing in MMA fights so its not as if he has been sat on his bum for 20 years, his own style is still as natural to him as it was back in the day. We have been searching the house and just cant find this bloomin license now and it a bit embarrassing lol! Thanks for your replies. ps As for his old club his instructor has now passed away so the club no longer exists!
