Root [Virgin Mobile/Sprint] Folder mount


I'm looking into installing a game that is almost bigger than my internal memory. If i move all other apps to sd via link2sd it will install on internal with less then 50 MB to spare. The problem is the obb files wont get moved with link2sd. I`ve read folder mount can remedy this issue but my VM F3 tells me i have insufficient space to install this particular 1.5 MB apk even if i dont install the game yet and have more than 700 MB free. I`ve tried booting into recovery and wiping cache and dalvik but still same insufficient space error from play store and sideload. I'm currently using Xclusive's v7 odex stock. Anyone have any thoughts or am i just SOL?
