Clapton Wire

Hi Guys

I'm soon to be getting a Limitless plus tank and I have been watching a good few builds on this tank on Youtube and most of them seem to be using Clapton Wire. At the moment I am using the normal Kanthal wire I think its 26AGW. So my questions are. What would be the best size wire to get for this tank and how many wraps would I need. I should have also said that I will be getting the ready made wire and wont be twisting my own.

Thanks
