Glad you are past the worry stage.
I like the Lynx. Because you can slip on an adapter for an MP.
But to answer your choices. Well You could use the Calyx wet or dry. Where the Helios is just a mouthpiece. Get a simple or several MP's from Dhgate that suits you. (As long as it's 18mm.)
I do want a matrix style hydrobomb from either Vapexhale or equivalent aftermarket. Just KIM that some don't fit as well as one that is designed for the brand.
I have some simple 18mm 4" tube socket that shotguns whatever is in the EVO.
Guess they are made to be formed into other pieces. But def a shotgun on it's own.
Here is a
US Ebay listing. FWIW
