I used to have a Diztronics TPU case on my past Razr Maxx and it fit fine in the holster from the case/holster combo from VZW. I imagine is work with with the G2 as well. @NewAge: Does the Dual Pro add much bulk to the sides of the G2. I know it does on my Droid Maxx. Way to bulky now. That is why I like the feather. Though it doesn't offer full protection. @Astrix: Let's see some pics of that SGP case installed.
