Regarding scent throw...bes sure you "cure" your candles a MINIMUM of 1 week...and I mean 7 days!! ;-) More, if you can. I was a parrafin person and was sceptical about this whole "curing" thing at first (I thought it must be an urban myth or something!). But, sure enough...the longer you let it sit, the stronger it smells!! Some scents will just never work in particular waxes, though, no matter how long you cure. And some waxes are more "particular" than others. You just have to do alot of testing. Good luck!
