Sounds like we're headed in the right direction and I'm glad you found something that works for you now
The Velocity RDA is known to be a great atty and I believe it can be tuned down well for less power while still making very nice flavor. I've had one for a few weeks but I haven't actually tried it until now.
Normally I set up for around 40 watts using dual coils with either 27 or 24 gauge Kanthal as that seems to be my sweet spot. I can get a good vape with those builds between 35-45 watts. Tonight I decided to try the Velocity at lower power for its first build and went for 30 watts.
Here's the build in SE. Dual coils using twisted 31 gauge Kanthal aiming for 0.5 ohms. I didn't think I could do this with my 27G Kanthal and I had the 31 gauge, so I went with that. I'm vaping it now at 30 watts and IMO it's
very good. It ended up at 0.6 ohms, but I'm inexperienced with twisted builds and also vertical coils so that's what I'm blaming for the inaccuracy

. Here are a few shots of the build.
Non-contact coils (I like that for better flavor):
Wicked with Koh Gen Do:
The lower air slots are not opened wide and the upper are closed. I opened the slots a little more after a while:
I'm really liking this vape at 30 watts. Similar flavor and TH I'm used to with my typical 90% PG juices at 40 watts. It isn't as aggressive a vape as I'm used to in that it doesn't vape as fast, but I'm going to give it some time and see how it goes. I will also see how the twisted wire stands up over time. I'm pretty sure it will reduce my juice consumption if I stick with it
A similar build could probably be done using 27 gauge Kanthal, but it wouldn't be the same. Ultimately it's up to you to try things and see what works best for you. The devil is in the details
