The range is very wide for what kind of build can work in it… You can play with everything from RDL to power DL.. I tried Alien and another kind of full DL coil in it and it produces such bad stuff 
but unfortunately the drip tip does get hot.. for my part.. since the amount of vapor is a secondary factor for me, RDL remained the winner for me… blue wire 3mm core 5 wraps slightly spaced 20-25 watts
