I use to have the otterbox on my torch and decide go without a case because the OB was making the slider a little loose.
Son after looking I got the AGF GTR and its the best cases in my opinion, so if you are looking for a cases go with the GTR its well protected and dont damage the slider.

+2 on AGF!
Picked up a "seller refurbished" unit from ebay at abt 10 USD, free shipping. The case is solid, and fits in the "default giveaway" BB Koskin holster for Bold/Tour. I later ordered a new AGF leather holster for Bold 9000 from another vendor on eBay, for abt $8, S&H included. It fits (although snugly) and works beautifully on "sleep in holster" feature.
I have a AGF GRT case and it's great but for years I used a Monaco leather flip case for a Pearl. It protected the screen and keyboard and I also used it as a stand. I never had issues with dust inside the Pearl.
I have both the AGF GRT and just got the AGF Endo and love both of them except for the fact that the holster for the endo could be designed a little better.
