I'm 5'9" about 165. Koral A2 is the only size that fits me well. Any other A2 will shrink too much in the arms and end up fitting too tight and being really short in the arms. I love the Koral.
The A3 size in most brands of gi fits the length of my arms, but otherwise is entirely too baggy.
Go with Koral with your build, especially if you've had trouble with arm length in other A2 gis.
