I'm a little confused on all of the different "set up so people are using like flexicone, ring, basket, metal ring??
It'll work right outta the box. It only gets better with a little bit of tinkering and thinkering!
The flexicone is a small silicone nipple looking thing. This is used in 90% of setups.. Alternatively there is a hard Teflon cone(kinda unanimous on here that this doesn't seal quite as well as the flexicone)
Next up's the flexicone plus.. This is a version of the flexicone but six or seven inches of tubing formed with it. This is mostly used in conjunction with the screw on lid.
The baskets are referring to the small meshed baskets you get with the MV.. There are large and small versions.. With the added option of picking up some medium sized baskets from any headshop stocking arizer EQ tower accessories.
The baskets snap into both the flexi and flexi plus before being placed into the chamber of the core(chamber can also be packed directly though this is considered a far messier optoon) Out of the box are also the flat cap screens that sit atop the open end of whichever basket you are rocking before attaching to either flexi.
Rings are referring to either the Teflon set(supplied with the Teflon core MV but not the Glass core) or the aftermarket stainless steel(Decarboxylation? Kit)
Confused? Lol.. The rings actually line the chamber.. The metal set add an element of conduction and that means a slight drop in flavour im(and many others)o although does produce faster hits with less priming of the load necessary.
As I said it works straight outta the box.. There is no box!.
But the further you can find yourself thinking outside of the box the more fun the MV becomes.
Any other queries.. Just shoot bro.
I should add that should you have/get a glass core MV then the Rings are not relevant as they cannot be used with this version. The glass acts similarly to a Teflon core fitted with the metal rings.
Adapters for attachment to watertool is a whole other subject.. There are many options.
