It's okay to get a regular 510. Typically I use a LR 510 bridged, but the bridge-less is fine as well - some say it's better. All the info that our sweet mini leopard is giving you is really good info. In my experience, atty's really give a "close as you can get" to the flavor/vapor perspicacity. You'll know when it's time to add a few more drops because the taste changes and it can get harsh if you're not attentive. So many ways to puff n stuff!
