Just Aikido, no style. Or at least what we (as a group and as individuals) perceive as Aikido.
From my observayion the student testing has fluid movement .He appears to be fit . His varied ukemis is good-quite athletic.His Aikido unfortunately leaves a bit to be desired. I for on do not think he is too proficient at basics.He lacks precision and his waza lacks good form. Could do with tightening up and going back to study the kihon waza in greater depth. Sorry to be critical but I hope my comments are seen as being constructively critical.Tell him to keep on and polish his art. Cheers, Joe.
