The cylinder sounds like a good idea. The only real reason I want to try weight is to make it quicker and easier and less messy, which a cylinder would accomplish to an extent as well. I really don't enjoy syringes and my DIYs take forever. But for now, my goal, for being a lazy sloth, is to mix a large batch of 6mg unflavored, and just mix flavorings into that. Because, I vape <6 up to 6, a combination of 3 and 6 each day; so whatever nic ends up in a bottle between those two is fine. This will make trying flavors a lot easier and quicker, since I'm lazy, and haven't found many if any recipes I want to duplicate yet. So being able to just mix flavorings into the base and be done, would be cool until I get a few recipes I really like. Then I can go hog wild with bigger batches and probably ditch the 6mg base method.
