Thank you for taking the time to check out my post. I recently upgraded from an SVD/iClear30 to a Nemesis clone/Kraken clone (both from eBay but overall decent quality), and am having some trouble with the white center post insulator. It looks like it starting to melt. I'm using dual coil set-up with SS mesh (350), 28g kanthal, and a Sony V4. It comes out to about .7-.8 Ohms. Nothing too extreme. I also noticed am I not getting the vapor production I was expecting (but the flavor is definitely there). Any advice on what to do? Can I go to Ace Hardware and buy a Delrin replacement insulator? I know that someone here will know. Also, how can I get more vapor production? I'm not looking to enter any cloud contests, I just want a bit more satisfying vaping experience. I'm using 50/50 PG/VG blend and would like to stick with that if at all possible. I've heard increasing the VG produces more vapor but that it doesn't wick as well. Any thoughts?
