i would look for a very small piece of debris in the tire, such as a bit of radial wire, or some frayed derailer/ brake cable. they can be nearly invisible, and protrude into the interior of the tire just enough to slowly scour a pinhole in your tube. this is a great example of why simply running your fingers blindly around the inside of your tire is kind of nonsensical.
