Mold minimalism is good, but it's not good for its own sake. I struggled with minimalism for a while, trying to reduce the number of molds in my bag not because that was helping me on the course, but because I thought I should. It took me a while to get to the point where I had the right discs in the right stages of wear and to get to the point where I was throwing well enough to benefit from that.
I think it's kind of funny how people talk about seasoning their discs on this site and they act like that's something that happens in a month or two. In my experience, it's taken years. I still throw the same TB, Comet, Buzzz, River, Ion, and OLFs that I bought years ago. They are in the perfect spot right now for cycling, so that I have a wide range of stability with only a few discs. I have a flippy Ion and a stable/overstable Ion. I have a flippy Comet and a stable/understable Comet. I have a stable to slightly understable TB, a stable TB, and a stable/overstable TB. It takes a long time to get your discs to the point where you can fit a bunch of slots with one disc.
Mold minimalism doesn't help you if it's driving you to replace a Teebird with a Banshee. Those two discs are not interchangeable, and the Banshee will perform poorly in the TB slot. What's wrong with throwing a TB and an FB? Why try to replace two classic molds that coexist beautifully in the bag with a single mold that's going to come up short as a replacement for not one but two molds?
So my advice is to pull back from the mold minimalism a bit. Throw what is useful on the course, and let your bag evolve into a minimalist bag if that's the direction you want to take it. But mold minimalism takes time to do properly, so keep that in mind.
