Full Sleeve vs SS aero top

I will be wearing kiwami amphibian tri suit with an aero top to put on in T1 and take off in T2. Looking at the castelli T1 short sleeve to my elbow or full sleeve kona top. Like idea of full arm coverage but fear the idea of trying to fight with it while trying to get it on while wet (could create more wrinkles and bunching). I have messed with the T1 top wet with little fight. What are benefit to a full sleeve? Andre, can you give any insight why Kiwami decided to make a full sleeve instead of a SS like other companies have been doing?
