Does anyone use a high voltage PV with V4L cartomizers? I tried looking but couldn't find a thread relating to the topic. I have a 5v GLV2 from Great Lakes Vapor and have given up on pretty much everything except dripping. I tried some LR atomizers when I used a 3.7v but they weren't that great and had a burnt taste. I'll spare the suppliers name. Someone recommended I check with V4L but they use a 3.7v and couldn't say about using a HV mod. I really like my 5v and wanted to hear from someone who uses one with Wow Cartos. I think I'm going to order some 555 and Cowboys to start off with. Any direction to a thread or replies with advice would be really appreciated. Thanks!
