What would bigger air holes do on a greatly built rba? Almost all vapers here in the Philippines are pro at rebuilding already, since it's probably the most widely available atty here, and it's really popular. Same as mechs. But I don't get it! People here are crazy about Air holes, they say the bigger it is the better. But for me, a 1.5 mm air hole is already too big. 1.2 mm is what I find the best, but almost everyone goes for 2mm, some 2.5 or 3mm, and I also saw one guy who has multiple RBAs with 4 and 5 mm Airholes! like wth? how is that so satisfying? though they produce godly amounts of vapor, even with high PG juices. It's like looking at real nimbus clouds when they puff it out. is its point only for more vapor production?
