I, also, had over 100 fragrances tested in 415 before the changes which I saw with my 2017 batch. I think I now have about 50 tested out and am weeding out some(still have some older wax for that) and trying to streamline a little bit. That change did almost cost my mental health, but I have been pretty happy with the 'new' 415 and my product, after I got my wicking figured out. My 2 batches of wax from 2018 have been very consistent.
I do depend on the candles to supplement my income(hay for 25 horses), so I really didn't have a choice but to figure it out. Can't imagine starting with a new wax, I've used only 415 for 12 years. What wax did you end up going to?
That all being said, I did order another pallet, wish me luck.
