I currently have a 2XU Comp Sleeveless suit. I am wondering since I am entering some early spring events (= colder water) if the sleeveless will make a huge difference in 3 ways: 1. body temperature, 2. bouyancy and mostly 3. speed. Any ideas? IF a full sleeve suit will make a large difference (we're talking for HIM and IM's), any recommendations/deals you know of? THANKS!
