I'm used to drilling attys so after watching the video gave it a try. I didn't add holes on the opposite side but drilled both side holes to 5/64th and the chamber holes to 3/32. Modded the inner delrin pretty much like the vid to distribute the air evenly to both coils. I also didn't drill the chimney as it is already really close to 1/8th.
Results are great! I already loved the Aqua and now my modded one has a draw similar to the Fogger on fully-opened. Compared to my un-modded I get more clouds but flavor is lessened a touch. This is a fun modding for an already great atty. Thanks for linking the vid dUb.
