TheDigital, you can twist a strand of Kanthal in with that nickel to get a thicker vapor. You need to figure out your ohms first, though, as you will see a wider spread in resistance with a Kanthal/nickel hybrid. Your TC won't be quite as accurate, either. Get familiar with a nickel only so you can be prepared with a hybrid.
You may want to adjust the 510 to make sure you are making a solid connection, too.
