So far I have not used shock mounts for these mics and didn't think I needed them. However, I recently recorded a quiet show clamped to a metal balcony rail, and I can hear when people bang on it. I record from this spot a lot and would rather spend the cash than stress out when people have a good time and express it through contact with the railing. I would consider spending the cash on the Neumann mounts but they don't seem like a portable solution and may their size may hinder some stereo configurations. Was looking at the Rode shock mounts but don't know if the sm1 will fit the u89's diameter. Put an email into the rode peps and waiting to hear back. According to Neumann the 89 is 46mm in diameter. Anyone out there have any personal experience with a shock mount that will fit the u89? Any help would be great, thanks, Ed
