Yeah I agree.......a real BJJ school does train with the gi.......it is traditional for one and two it gives you handles to work with. I don't know too many people that walk around just in shorts other than at the beach. Plus in winter time people wear lost of clothing so gi training gives you a lot of options. I choked a guy out just by using his Polo shirt and I also choked a ganbanger with a cross choke using his Pendleton jacket. So gi training is important.
