The DPA kit uses a combination of very soft Lyres, which work well - but in some cases are felt to be too soft for boom work.
The 4017c is compatible with our standard WS 2 kit (details below). Our standard WS 2 kit also uses soft Lyres, but slightly harder grade & much better for boom work.

You can purchase the suspension only for the WS 2 Kit:

This will allow you to get the Windshield components at a later date and build up the kit.
If however, you are after a shock mount only for the boom pole.
