Max Hybrid and Rocky DL Results

This is a comparative evaluation of the Cimbali Max Hybrid and the Rocky Doserless. I used fresh Intelli Blackcat (no signs of oil on the bean), roasted a week prior (can't remember the exact date of roast as I'm inserting this information after the fact).

I'm trying to determine why I see, what I consider a good amount of clumping with the Max Hybrid. I've read reviews with people saying it's clump-free, etc. and I don't want to resort to WDT. It just cramps my style. :)
