My bag changes from course to course, if it's a longer course more distance discs go in, if it's a shorter more technical course, more Truth's or fairway drivers go in. The main reason for all the molds is pretty simple. I have so many more options now than ever before. With DD/Lat/WS I'm still finding new driver to try out...not to mention the fact this ITB was done in Sweden after visiting the factory, so of course some new drivers, blanks are going to make it in there...
