Supporting vertical copper pipe

[roundrightfarm]

What's the best way to support a 25' vertical run of 3/4" copper pipe? It is a hot water line and will be insulated. It will elbow near mid-joist depth both at the top and the bottom of the run, and is next to a 3" DWV stack, making blocking between the studs difficult.

Thanks

Sometimes you can add wood for blocking on the stud nearby.
