I've got a Brooklyn Gear and a Comfort Strapp and like them both. I use Boston straplocks, similar to Schallers, much cheaper and they have two slim nuts so the nuts can be locked and don't work loose like Schallers.
Quality seems to be at least on a par and interchangeable too.
I did have an Overwater strap but they work in a completely different way to the Comfort/Brooklyn straps with the stretchy bit is a single piece of elastic attached to an otherwise non stretchy pad. My bass neck was doing nodding donkey impressions.
I do wonder if they may have been modified?
