That looks like a nice deal, BUT have you ever played with a strap that wide? I have a very nice 4" wide strap that I bought but it's unusable for me. The wide width irritates my neck. Just something to consider.
That being said, if a 4.5" strap is for you, that looks sweet!
I've found that to be true for me too on most 4" or larger straps, although I've got one that doesn't do that.
