I'm having trouble with my Paps SS V3/Heron combo but i can't figure out the problem. Seems like i'm getting a lot of voltage drop or something, it's just not hitting as hard and smooth as it should. I noticed that if i press certain areas or sides of the switch it seems to perform slightly better than if i press other areas but even then not as well as i feel it should. So, i thought it was a problem with the switch but if i use a different topper like a KFL or a dripper with the GP top cap it works just as good as when i use those toppers on my other mods. Okay, it must be a problem with the Heron then. However, when i fire the Heron on the regulated mod it hits great, when i fire it on a different 20x1 threaded mod it hits great, and when i fire it on my Lux edition Paps V3 it hits great. So, by themselves they seem to work great but as soon as i put them together performance lacks. Threads and connections are buttery smooth as with all my GP gear so i'm lost as to what might be the problem. Wondering if i'm missing something the GP veterans can help me with? Any help is much appreciated.
