Hi everyone.I am looking at the Lavatube as my first kit.My pre-ordered ego w kits from the north has yet to arrive.Not able to wait any longer,I asked Hubby to buy me another kit instead.He finally agreed to the Lavatube.My question is,what extra parts should I get?How about the catty or atty(hope Im right)?Which is best for Lavatube to enhance its performance.I read something about a 'coil head and a wick.'May I know what that is?Though I did read also that using a wick might be dangerous.It could explode?Please correct me if Im misinformed.Any information will be useful.I will be placing an order but have no idea what to add on.I will truly appreciate any feedback.TIA. PS:Im a newbie.Kindly hope you will use layman terms.
