I run the m100c with AKG caps. and really like the ease of setting up your configs. Three negatives, however, are:
1. To shock mount it using one a20s, you need to have this little barrel insert to go in the mount, then you need to run the m100c at 90 degrees...this makes for a somewhat flimsy mount--the m100c is kind of heavy and that plus caps, all being held by one a20s and with all the weight out in front of the a20s makes things a bit precarious.
2. It's not really low profile...it is not hat-able like some of the fixed bars are.
3. I also wish it could extend farther so you could achieve a little more space between the caps.
