Okay, so I'm sitting down now with my brand spanking new Reo and getting everything ready. Atty is built (went with a 6/5 wrap, 2.5mm ID, 1 ohm coil, wicked with KGD) and ready. Bottle filled. So here come the questions again: cutting the inverted v in the bottle tube. How big does the cut need to be and do I only need to cut one side of the tube or do I need to make two cuts? I'm guessing one since making two cuts would pretty much eliminate the bottom of the tube but I want to make sure. Also, can I use any eraser to clean the top of my battery? I watched super_x's video and he said any eraser but I also read elsewhere that it has to be a specific type. He does seem to be the Reo guru so I'm not doubting him, just making sure. I have a Sony VTC4 fully charged so I guess I'm gonna go with that one. Really wish I had the AW batteries on hand instead of sitting at the post office but such is life.
