I’ve used the Cuore trisuit in a couple of triathlons. I really liked the fit, medium, 5’ 10”. No wrinkles in the shoulders and didn’t ride up on the legs. What I did enjoy was the small padding, didn’t notice it on the run. What I didn’t like were the two side pockets they were pretty small. Had a bar and gel fly out during a bike and a run.
I’ve heard good things about Velotec suits. Apparently they test really fast, aero wise that is, per Jim at ERO. I don’t know anyone that has bought one though.
