He also throws cd2s time to time.
But I think that a lot of us naturally have the core of our bags based on only a handful of molds. The basis of my bag(and probably most innova-centric bags carry at least most if these) is aviar, roc, teebird, thunderbird, firebird, destroyer. But that doesn't keep me from carrying an md3, leo3, roadrunner, and pd to fill more specific shots that I can't get/it's too hard to get out of a disc from the core of my bag. Ex.-md3 is 90% forehands, leo3 is for tailwinds, roadrunner for rollers, and the pd is to the thunderbird as the eagle-x is to the teebird for many others(shotshaping ability due to its small turn and hefty fade).
So I don't think that philos bag is much simpler than most of ours, he just doesn't have any discs that r just for a specific purpose like many of us do
