So I am gearing up to get my first Spyder. I am thinking a left over 2014 ST-Limited instead of a RT will be the way for me to go. But I need to get a new helmet. How you do feel about 3/4 vs full face helmets on spyders. My thinking is that full face is not as necessary on spyders. And one other challenge - does anyone know of a good company that makes a 4xl open face helment (with full shield)?
