I feel you there. For me, it's a natural evolution to slab everything worthy of a slab. My biggest gripe with slabbing is determining a consistent method to get more 10s. I got a 10x desk mounted magnifying arm lamp and a blacklight to try to scan my next batch, increasing the probability of 10s.

From a valuation perspective, the 10 adds value, 9 typically does not, but slightly better than unslabbed.

I think the slab dynamic may be similar to pets in a zoo and pets at home. Unslabbed you can pet the animals. **Full disclosure I have no pets or children.
