I finally talked myself into adding one and for personal reason I chose the Elite because I didn't want a hose hanging down from it with the chance it might get caught in something and the other thing was that knowing me I would forget and leave it open after draining. About the breather, I think it is not necessary from what I have read. I thought I had read it might be more necessary to have it if you were SC or running a turbo, I think, but don't quote me on that.
