Hey, hate to butt in on this thread, but I'm also testing wicks in 464, and I noticed the LX30 I had in a 4" dia. jar scented with Vanilla got a huge 'shroom and started wanting to drown after about 3 hours, while an LX28 in the same size jar with Lavender was doing fine at the same point. I've bought Beanpods that have done the same thing, but I don't want mine to! I didn't realize different fo's made that much difference, but of course, if they didn't, this would be all too easy, wouldn't it.
