Raquesh, the recommended wattages are just that: recommendations. They aren't cast in concrete. The reason folks are suggesting you start low and increase wattage little by little is because every juice has a "sweet spot" for every vaper. You may find that you like your 1.2 OCC at 12 watts or 14 watts for a particular juice. And that's great! With a lower ohm coil (say, .5ohms), you will want higher wattage. Again, though, work your way up, bit by bit. Enjoy!
