First-hand experience..........not something I read or someone told me: 10 years --- approx. 50% pine bark and 50% inorganic. 30 plus species including topicals, conifers. vines, deciduous, broadleaf evergreens. Absolutely stellar growth and health. No one can dispute what I've experienced. I say if what you're doing is working, stay with it.
