Hello, I am interested in getting a 184sm and was wondering about sizing. I have a 118 50 long, and the back length is right on the edge of good/very slightly too long, but the sleeves are a bit too long. I had tried a 50 regular first and it was the opposite, back length much too short, but sleeves were right at good/slightly short. I'm trying to decide if I'd be better off with the 184sm in regular or long as I noticed they're 27"/29" as compared to 26"/28" of the 118. I'm 6'1", 260lbs, and my sleeve length is somewhere around 36"-37". Thanks.
