I have been vaping for a relatively short while, and am looking at getting a water setup, and adding the Liger 3.0 system in the future. There is so much information and so many products that my head is spinning and have a few questions if anyone would be so kind to answer. I’m so OCD that I feel I have to read everything I can find, but that just leads to more questions. 1) What are the advantages/disadvantages of the intake in center of rig vs on a separate arm? 2) Is it better to buy one with a 14mm connection for the vape(s) I have, or an 18mm and use an adapter? Would it be more versatile for possible future purchases if I purchased an 18mm? I currently use the VapCap products and the Arizer Air which need a 14mm connection. 3) Male or female connector for the concentrate setup? I’ve read that the male connectors can expand and break the glass, but not sure if this applies to the Liger system or other concentrate setups, or if it is even an issue. 4) From the cca710 site – Zeus Nail coming soon – what is this? Please advise if there are any other issues I need to know about before I cut loose and start buying. I really want to purchase the correct setup for me from the start, as I don’t have a lot of money to experiment with a lot of different setups, nor do I have the room to store it all. Thanks!
