Choosing between the two I would most deffinately go with the Sidewinder LX at this point. I haven't had a chance to look at the new Dusk Devil, but from what I remember with the original the pin gaurd was made of plastic. I wouldn't want that on my bow. I don't know where you hunt, but where I hunt my equipment tends to take a beating from the brush, branches, etc. An all metal or alluminum pin gaurd is what you're looking for. At least that's what I prefer.
