i bought the bodyglove case. it's ugly, but me likey. and with the Tetrax system it is perfect. here's why.
here's the case:
the hole you see is where a belt clip would attach or if not using a beltclip, that is where the plug would go.
If you take the plug out and remove the rubberized coating from it, there is a smooth plastic surface perfect for mounting the second to smallest disc. as seen here:
once that plug is snapped back in it is now officially an awesome combo. the disc is flush and only the bubble sticks up but it's barely raised. (unless of course you use the belt clip. if you do this combo is not for you.)
