I wouldn't recommend starting with 22g... ...it's really not something a newbie should be playing around with. It's very low-resistance wire, mostly limited to very hot, high-powered, cloud-oriented builds. It's hard not to build too low with it if you don't know what you're doing. It's really best saved for a dual parallel box mod. Play around with 28 and 24 first.
And if you're talking about doing two parallel 22g coils at 5 wraps on an 8th, then no, that's not safe on ANY setup. That's well into the super sub-ohm range (I'd venture to guess somewhere around .08.) A single parallel at that size and number of wraps is still probably going to sit a bit below .2. At that range, you really need to know exactly what it reads out to. It's going to be right up against, if not over the 30-amp limit of your VTC. That's not a range to be toying with if you can't even check your ohms.
Sub-ohming, in general is not "safe." Nothing about vaping is safe. It's all a matter of degrees. You have to make every effort you can to ensure that your margin of safety is as high as possible. Don't rush things. Don't skip vital steps such as checking the resistance of your build and making sure that it's not pulling more amps than your battery can handle. The VTC5 is a fantastic battery. But just because it can take some abuse doesn't mean you're safer using it haphazardly in an unregulated device.
An ohm meter is not an option, it's a necessity. Please buy one that can read down to the hundredths before you do any building, especially with that wire. It's one of the cheapest things you can have in your repertoire, but it's also the most vital.
