Kevin - I used the Sure mounts with my old Nak300's and also ran right angle XLR's. They will still try to pull the mics downward, but if you use the velcro strips you can secure the cables to your stand secure enough to prevent this from happening. Or you can just loop the cables over your t-bar to also reduce the downward force on the mics.
I liked these mounts. They are low profile and provide good shock isolation. One of mine however did crack and this fine white powder would "poof" ouf the the mount was flexed back and forth. I had to seal the cracked mount to prevent this mystery powder from entering my mics (real worry).
Just secure the cables to your stand and you will be golden!
