Hey Sandy, sorry no one else is answering your post. I think this may just be the nature of the beast in regards to vaping in general. It simulates smoking but is not exactly the same feel. The technique of the draw of vaping is slow and light. Maybe a different PV would work better? I really don't know if there is a stiffer draw, but I think you might do better asking this in the "General Discussion" thread (Normal Threads) where more people would see your post. Hope you find your answer. Take care.
P.S. Maybe you shouldn't mention "Kgo" in the title of your post as I think your question would apply to most, if not all PV's. That way, non-Kgo users would be more likely to respond as well.
