What are the dimensions of your bonnet aperture? Can you take a side-on pic? To fill mine, I think the 150mm filter (C604D) would have to be a good deal fatter than my C603D:
I'd also be a bit concerned that the extra exposed filter at the front would suffer significant abrasion from the air stream..
Just got some pictures of the filters together , you can see the difference is pretty big. The 150mm bulges out much more in every direction, which is why I think it fills the bonnet cut better!
