I took my TM30 to the machine shop at work and the machinist cut the top cap out for me so it can use 810 drip tips. It really helped with airflow and flavor. I really don't understand why they don't do these simple modifications from the factory. I now have some great RDAs to squonk with. The Elite gen 2 is stilk my favorite. The TM30 has moved into the number 2 spot with the Sherman running a close 3rd. I'm still trying to figure out a bf pin for the Buddha v2. I need a bf pin for an Icon that will fot my Mason. If anyone has a bf pin fir an Icon they are not using and would like to sell please pm me.
