I only have great things to say about my LG vortice. I had 2. One saved the entire side of my face and my skull ina pretty bad accident at over 20mph. The other I use right now and it is a champ. As far as protection goes it is a great lid. Only problems I have with it performance wise, is that it is a bit bulky and the bloody lens just fogs up in cold weather and eventually after sweating all over it the lens it became a bit blurry. My head never overheats on hot days and when I tuck low for the aero position everything just quiets down and becomes smooth. I use to have a giro air attack as well but that thing had the wind howling in my ear and offered no side of the face protections and barely any aero benefits unless you kept your eyes on the ground.
