Im with Luci. I have used the 4625 for a long time and I have great hot/cold throws. I use oils from Peaks and Just Scent and they smell awesome. I have never used the 4794 either but I may try it just for experiment reasons,, Edited to Add: I use Primed 24ply flat braid for my pillars 44-18-24 zinc for my votives,,,,
