I should have got this sooner!
It's truly amazing how much difference a great sling makes. I've been playing bass for some time. I've spent a lot of money on quality instruments but not straps. Until now that is. I have this paired with my new ESP bass I purchased from Sweetwater. I loved the strap so much that I just ordered another one for my German Warwick.
This thing is built like a tank and makes a heavy bass feel a lot lighter than it really is. It also doesn't hurt your shoulder like some more narrow straps. Stop thinking about it buy it. You won't be sorry! You will probably want another one once you try it so don't say I didn't warn you!
