I tried the organic cotton + wax combo the other evening through my d020 and it was VERY smooth. Thanks for the help guys! Maybe I'm late to the party or maybe I'm a crazy person, but has anyone used something like the 7th floor flavordisc with the Nano? The small size from 7th floor looks to be around 1mm larger than the GonG for the Nano. Could I order those and slightly modify them to make them fit? Is this a bad idea? Is the cotton just as good, if not better?
