Which style or system? There's quite a few types of Hapkido out there. Those two Hapkido schools I showed as examples are certainly not quality. I wouldn't be sending my loved ones there to get any form of MA instruction, that's for sure. My standard is seeing what you're doing and comparing it to what others are doing. Frankly, striking and grappling are dead give-aways to the quality standards of a given system. If you got a bunch of goofballs doing nonsense and those goofballs think that nonsense is awesome enough to advertise on the web, then something's seriously wrong with what they're doing.
