So after careful consideration and lots of thought I'm thinking of giving a local bjj school a try. I'm a newbie to bjj but I did do Chuck Norris style for almost 2 years. In standard karate I wore a size 8 Gi and size 6 pants. The school owner, who I've talked to online says he'd have to take a look at me to see (that is if I decide to stay) and he has wholesale Fuji prices. I'm 6'8" 275 lbs...would I wear an A5 or A6?
