Nope, don't have the tools to do so and wouldn't want to, either. Have you noticed a change in flavour production after enlarging the inner hole when you use it for MTL? In my experience, choking the airflow first, then channeling it through a large hole does not get you to MTL tank flavour production - there are countless tanks that claim to be able to do MTL, but they all fail in this very feature. What works a lot better is choking it just before hitting the coil, i.e. at the inner air flow outlet. The reason seems to be air flow velocity - from small to big hole the air flow is really slow around the coil, from big to small it's hitting the coil fast. What's your experience?
Apart form that, I can't handle anything higher than 25W as of late, dunno why.
