I bought this saxophone strap for my 9 years old son. He had an old BG strap, but he was never confortable with it and would make long session really hard to go through.
The Neotech Super Harness junior seemed like the answer we were looking for. And indeed, the shoulder padding distributes the weight of the sax much more evenly, making it easier to carry.
There is a big problem with this strap though.
The should pad goes around the back of the neck and forms like a colar that is open in the front. The issue is that the padding is sitting tight against the neck and pressing against it. After long sessions of playing, this lateral pressure of the padding will hurt my son's neck and leave marks on its neck.
So... all is all... it is promising and there surely seem to be several good reviews around. For my son, it's better for the weight... it's horrible for the neck.
