Thanks for the input. I don't think I'll buy a new sight until I can check one of these out. As far as corrosion goes, I'm not too worried about it. I think I pay enough attention to my bow to catch a scratch if it happens. And if it does I'll just dab some touch up on it. Thats a bridge I'm really not worried about crossing just yet.
I really like the sound of the light chamber. I'm going to call "Southern Hunter", my local pro shop right now and see about an availability date.
