I have three of those as well! One brown and two black. They are very are great quality and great looking. However, I like the idea of attaching at the billets rather than the D-rings since the D-rings can pop right out if the saddle really starts to go sideways. I have never had a saddle slip more an than inch or two, but prevention is worth a pound of cure as I get older, haha.
Well, I tried to edit this, but ended up adding a new post below. Oh well.
