Trust me friend, I researched TKD alot. Net, books, media clips, articles, peoples opinions.

The same punches in boxing can be used in TKD and still called TKD.

As for Krav Maga, I dunno, only went by what I head.

As for McDojo's, London has tons of them. I went to one, which I found out closed maybe 5/8 years ago. Feckers charged me and my bro a ton for TKD.
