Can anybody with an A3 measure the slack in the arms?
Here's a pic of the GI slack measurement tool. Basically, they run this down the entire length of the arm and if the slack is too short, you can't use it to compete.
Obviously, your arms will be different sizes than mine, but if you're much heavier than me and have acceptable slack, then it will work on me as well.
Basically, the slack needs to be 2 inches or more. So pinch the gi starting at the wrist and moving down to the armpit and see if your slack is at least 2" throughout.
