High end? What exactly does that mean? Are you selling on Rodeo Drive? What's wrong with the tons of excellent FO's out there already mixed and ready to go? Try sweetcakes or scent works, that should be high end enough, at least in price.
Same here. Just tested the Christmas ones, used 2 CD 10's (Harmony Blend wax) and burned great. If you space them out correctly, you can get the corners with just 2 wicks. I have also used 2 LX21's.
