I'm looking to buy my first Gi, but unfortunately I can't find a store near me to try one on first... I am 5'10/5'11", but only 155 lbs. Would it be better to go with an A2 which meets my weight specs, or an A3 which conforms a little more to my height? Like I said, this is my first Gi so I don't want to spend too much. Any recommendations regarding an inexpensive Gi that would make a good first?
