The .51 dual I had on mine put out more intense flavor than the single .9 I have on it now, but it's still a very good vape and definitely a keeper for me.I get denser vapor and flavor with this build with 4 holes open instead of 6,
It's thick as molasses.
the delrin 510 adapter is fantastic at keeping the heat away from my lips with this derringer style brass tip i'm running
Just finished the same build on my manta, and WOW!! the Forge V2 Destroy's IT!!!
