Used the rapido quick release adapters last night. Not using them as the "quick release" as sold, but primarily as spacers, and 2 of them got my 391's and DPA UA0896 windscreens, in AT 8410 shocks and the AKG standard t bar, and the risers gave me just enough room to get one mic above the other...to run XY on that bar. Definitely a cheap way to get the functionality of the Shure A27M bar, in the AKG bar.
