So much excellent info/advice here from everyone! I'm a newbie and have been reading threads for the past several days. I purchased 2 PVs: a Joye 510 and an Ego-T. The Ego-T has the whistle-tip cart and I know somewhere I read about modifying the tip for more vapor/flavor. It had something to do with removing an inner piece, but now I can only find some vague mentions of doing that, not instructions or images/drawings. Can someone point me in the right direction to find the detailed instructions? I've watched MistressNomad's videos and looked at/read so MUCH stuff, my brain is like scrambled eggs at the moment. TIA!
