If your interested let me know and l'll let ya know the prices at the South chapter. You could always come out for a free first class to check it out. I would say keep the gi on, unless you are training for a fight. Think about it how many times have you fought someone(street) or seen a fight where they keep their shirts on or don't have time to take them off. That nearly doubles your submissions, sleeve chokes,collar chokes ect. Theres nothing like choking someone out with their own cloths.
