try out 24 gauge 9 wrap on 3mm dual coil see how that is at 50 watts might not have the "mustard" to heat it up fast enough should clock in around 0.3-0.4 ohms
next I would try a 24 gauge 10 wrap on a 2mm - 0.3 ohm range
then I would do 26 gauge 8 wrap on a 2mm - 0.4 ohm range
i find smaller diameter builds work better at lower watts in my velocity
best part is velocity so easy to build and wick you can do all three of these and test them in about 30 minutes
