is it safe to vape using my build? or can anyone help me build for flavor and clouds? im using dual clapton on an avocado24 bottom airflow and predator 228.

Each to their own. My go-to build is a dual 24g Ni80, 3mm, 7 wraps.. And if its a single coil, I either use the same setup or use a 26g Ni80 or Khantal, 3mm, 5 to 6 wraps

http://www.rapidtables.com/calc/electric/ohms-law-calculator.htm . The above is an online ohms law calculator that I like to use. If you enter any two known values the calculator will give you the other two. In your case .44 ohms at 60 watts gives you 11.67 amps at 5.1 volts, well within the capabilities of your mod. So you're good assuming that you have the optimal/recommended batteries for you mod.
