hey Buster...the only advice I can give you is #1. you got to have good high grade fragrance oils from reputable companies...#2. Oils that I like...are usually scents that most people don't like...some like moderate cold and hot throws and others like knock your socks off types that I can't stand...and most poeople on this board will tell you...you need to find a good wax and stick with it...and when you do...you'll find that some fragrance oils will knock your socks off and some that you really like will only have a moderate hot and cold throw... I have used a number of waxes over the years and I seem to always come back to J50 or 4786/soy blend... and I have even tried J223/and soy 50-50 hope this helps...You can usually find an answer for any questions you might have from the most knowledgable people in this forum.
