I voted no on having to study DTR. My thoughts on this, is while it may give you a better understanding of our art and the evolution of a species, it will not really improve it. Like studying Latin, yes it will make a more knowledgeable on our language and perhaps a shoe in as a life line on Who wants to be a millionaire. But will it make you an orator like William F. Buckley? Probably not. DTR is DTR Aikido is Aikido. DTR is simply not Aikido with Atemi. But a different system altogether. We can take this argument to the extremes too, i.e. should we as Aikidoka read the Kojiki to understand O'sensei's Doka??
