If you flash to a custom ROM, i.e. MightyMike's, Malatesta's, etc, most are very stable, are 6.5 and almost all if not all, already include tethering that is not trackable via carriers, so if you're holding off for that, fear not. Just read the first page of each chef's threads, paying attention to what is included. Many may already have some of the tweaks or apps that you're currently installing. If not, the threads that Austin linked to above will help you grow with the knowledge of having your phone auto install things you want, or for time being, just load them one by one after you find out which ones you actually now need. Good luck.
