I competed in kodokan judo in mid to late 90,s and did the east coast judo championships 3 times,i didn't win but placed decent, I got to green belt level then left to learn the ground game with no-gi, I got my matches on VHS. my instructor was gold medalist mike swain and my dojo was in cranford,nj. I got sick of the gi and felt it wasn't practical in real life scenarios,if u r on the beach im pretty sure a guys not gonna have a heavy coat or jacket on to grab, then what? I like the karo perysian type of judo,no gi judo. I wont even do jiu jitsu with a gi cause its useless imo, I used to be a judo fanatic and yes I know who jigoro kano is,i read many things on the internet about him, I use my judo aand wrestling to get a fight to the floor and my submissions from judo/bjj to finish it.judo and bjj basically have the same submissions its just that helio gracie altered the moves very slightly to give a weaker man an edge on finishing the move over a stronger man
