I think this way because it's a blend that I myself have tried. I've tried 50/50 as well, and also a 70/30 of 4627/444. Even the high paraffin % mixture acted and looked funky. It seems that you've had a similar experience before too: http://www.candletech.com/forums/showthread.php?t=53004 I'm convinced 4627 isn't blend able, but I'm glad it's working for you .
