I used to fill and practically overfill, but now with that dome screen mod in the CU, i'm vaping loads of <.05g and loving the micro doses with this little bad boy! I didn't know I had a stack of these combustion screens that are maybe 3/4"? They dome up flawlessly in the CU! Either with or without the stock CU screen. I love milking up my bubbler with one nice fat tasty rip!
@Mr. Me2, I stopped using the cut screen on top due to all the scratches it was causing on the sides of my Mighty. With the Crafty it's been exclusively dome in CU and not a single scratch!
