Mandy88, are you looking for high VG for a particular reason? I am sensitive to PG and use very high VG mixes in my juice. I put a drop or two in my tank of distilled water when needed, and that helps thin the vape. If your preference is still high VG, you could still be using your old equipment. I started with a Nautlius 2 and that's really not designed for high VG. If you like long slow draws, what I do to help with consistent wicking is keep drawing a few seconds AFTER I release the fire button, and that wicks juice up into my coil consistently-- I never get dry hits.
If you want more VG for more clouds, I think there are better setups out there for you than the penguin, especially if you've used other vape equipment. You could look into getting a true sub0hm setup, there are some good, reliable models out there, fairly inexpensively especially if you don't want to do TC.
Good luck!
Anna
