Did mine in '91. Was going bad with basics, slippy floor and all that(so I thought), but I redeemed myself in the kumite. I was up against this other guy going for his black belt too (there was 8 of us grading at the time). As soon as sensei (dave Hazard) said begin I feitned a sweep followed by a jodan mawashi geri, obviously I used the instep of my foot (not full contact), The slap from the kick on his cheek was so loud it echoed around the dojo! Ippon!! We started again and i did exactly the same move! SLap! Ippon!! I felt really sorry for the guy I was fighting,his cheeks where looking pretty rosy:) Anyway the guy I obliterated and myself where the only 2 who passed. Sensei Hazard then said I should try and vary my technique a bit more but also commented on how well controlled I was. To this day i dont think Ive ever pulled off such a good roundhouse!
