So this isn't a mod per se but I was not sure where else to post this (moderators feel free to move as necessary). Anyway I just orderded some replacement carts from Totally Wicked, these are a totally different cart shape than what came with my device. They are totally rouned with the exception of two small vents on each side. they seem to hold more juice and are a much cleaner and fuller draw that the original semi-circular carts. Just thought I would let you know.
