The best holster product I have used (Treo; didn't have one available for 6700) is made by Helix. Very sturdy.

The Seidio holsters are not well reviewed. Verizon's holster for the 6700 was horrible. The clip at the top would launch the SD card whenever the device was removed. I have another generic holster from Ebay that is OK, but scratches the antenna.

I like holsters because of the easy access to a naked phone. I would most likely get an Invisible Shield or similar product that covers the entire device.

Vaja cases are very nice, but add too much bulk, IMO.

Mrailing, model yours off of Helix.
