Hi Meredith, and welcome to the "joy of soy" 1oz pp does not seem like too much FO, but may I ask what scent is it?? I mean, is it a lighter scent, or a darker heavier scent? IMHO, w/that wax and size jar, I would be looking @ an LX 20 or 22, or an RRD 40 or 47.....these are the only 2 types of wicks I've ever used. I'm trying to figure out why you would need that big of a wick in that diameter :undecided....oh wait- according to my pamphlet, the 415 is pure soy, which I have found to need a larger wick, so I would take my suggestions up a notch or 2. HTH
