I'm really pleased you're getting on so well. It is a liberating feeling when you realise you don't need so much mental and machinery baggage.
It is worth watching how your soils evolve as the years go by, as you say they they are prone to slumping. I was so certain that ours were getting better and better year on year, that I failed to notice a fault line developing just below the rhizosphere, ie 3 or 4 inches deep. This horizontal break was, we think, due to the silt slumping (we've got approx 30% silt in our soils) and made it hard for roots to penetrate deeper and water infiltrate easily. The worm holes go through, but it wasn't enough to stop yields dropping from their peak in years 1-5 of no-tilling, to now (11 years in).
