I just tried an interesting modification and was wondering if anyone had any thoughts on it...
I'm trying to make the 510/stem systems I have more reliable for my wife. She admittedly does not get nearly the practice I do, but she usually picks up even tricky vapes like the StickyBrick Flip before long. She's really struggled with the Imp. She has more success with the StemPod, as in faster more consistent clouds and less combustion. Her draw control is not very good, but she finds it easier to control with the wide open StemPod. She is also good with the DBV which has similarly open draw.
I very subtly widened the air intakes on my Imp just now. Literally just wedged in the long thin pin that comes with 7th Floor vapes, and it wasn't too hard to push through so I didn't take it much wider. But I notice a difference in sound and draw immediately. Much easier to initiate a hit (I'm on the old stem system, remember) without nearly so much priming. The lady is asleep at this point so the verdict with her will have to wait.
When I first got the StemPod, I had its airflow clamped down like the Imp's figuring it was working for me well enough over there, but we both had inconsistent results and slow lights. Once I got used to a wide open airflow on the StemPod and controlling it ALL with my lungs, I've had zero issues.
The Imp with old stems admittedly take a little longer than the StemPod to get revved up, but it seems faster and more capable of sustained high heat hits even with this small modification. I might go a little wider at some point.
Just found it interesting. Have you experimented much with the intake size,
@mistvaporizer ?
edit: Just went a tiny bit wider by wiggling the pin in the holes a bit. Even better. Hmmm...
