If it doesn't seem to be wicking quickly enough, adjust your wicking. Thin out the tails, give them a "haircut", whatever. 24-gauge is really too heavy for MTL - you've got more metal mass to heat up, and you'll wind up cooking your juice on both heat-up and cool-down, which is a good way to add some lovely formaldehyde to your vape. Getting up to atomizing temperature quickly is key.
