Only difference between the 13 and 15 that I can tell is that the 15 is smooth bodied. The 13 looks like it has more bulk and contours to the sides/face.Thanks for details on the bumper! As a follow up (sorry to hijack your thread into a thread about your bumper!), did you compare to the FS-13? I’m having trouble understanding the differences between the 13 and the 15.
It looks like the 19 might be getting phased out, and I had been planning on that but yours looks so good that now I’m considering it
They are very similar though.
I am into the stubby's. The 19 looks like it's caught up between a stubby and a full width. Mid's look strange to me. But that's just my little old opinion.
