I had the same problem as you with step cuts, being as OCD as I am, it was just not doable. I let go fast. I cannot stand dirt and grime and it really does affect most step cuts’ light performance greatly.
So hard as I would say upgrade your CBI but I know the Asscher ring is just so stunning! You have to do what your heart desires. Sleep on it, give it a bit of time. See if it just the novelty or you will continue to prefer the CBI.
