I simply can't imagine better bang-for-the buck in a strap. The leather is excellent -- thick and sturdy (putting on StrapLoks takes more effort than usual) but still soft and flexible. The suede backing is of the same high quality. Can't yet speak as to how the stitching will hold up, but the work is flawless.
Comfort is also outstanding. I need all the help I can get with a G&L JB that is obscenely heavy. The 4" width REALLY spreads the weight to where I've yet to have any strap dig into my shoulder whatsoever. I'm sure the quality of the leather helps as well.
The strap would be a great deal at full price -- on sale pricing was insanely cheap for this nice of a product. It's beautiful, it's well-made, and it's a shoulder-saver. More than a quality strap, it's a luxury strap, for WAY less money than I thought I'd have to spend.
