The ability to adjust your mics without rotating anything else using the adapter shown above is so advantageous to an easy set up.
I don't know if your stand sections rotate or not, but even if they do the adapter shown above is still one of the most helpful pieces of equipment you can own for practically no money.
If your stand sections do not rotate they are pretty much essential equipment IMO because I solo a lot in theatres I cannot block by myself so bungee cording instead of opening a tripod is a key part of taping. It is the best investment you can make in terms of misc "attachment gear" and you can put any myriad of washers and adapters you need on top to fit your T-Bar or a shockmount or pretty much any other accessory you will ever buy.
