I have two of the steel 8ights and they are great cans. If the titanium was available at the time, I definitely would have gone for one of the titanium 6ix+ . I've shot with the regular 6ix and while handy for hunting, I don't find the level of suppression to be as comfortable as I'd like. A little extra volume with the 6ix+ would be great!
That being said, very happy with my 8ights!
