Hi Boneybear. Welcome to the ECF
It's hard to say what Wattage you will like the Best. Lots of Variables going into things like Airflow, Ohms of the Coil, mg of the e-Liquid you're using, etc.
My Best Advise is to Start with a Low Wattage like maybe 8 Watts and take a few hits. Then Bump the Watts up .5 watts at a time taking a hit or 2 and seeing how it taste.
