Was able to change the Coil (3/32 : 28g : 6/7 wraps) and then REUSE the 3mm RxW. It was actually easier reinserting it being in used condition than when it was brand new. Could have been because I carefully removed the RxW from used coil, and slightly torched it clean, and then added a few drops of spring water to wet it once it cooled. I was able to squash it close together while rolling it with my fingers. This made it less dense and skinner - thus making it easier to stick through the new coil. Once in, I pulse dry-burned it 'till it was all white and new looking.
**I was never able to reuse any 2mm RxW pieces at all. It always broke in half when trying to reinsert it in a new coil. **
Bottom line, 3mm RxW is a lot more durable than 2mm RxW because it's thicker. The bigger density allows more dry-burning to clean coils; holds more juice which reduces dry hits; and I've actually have noticed a slight DECREASE is juice usage. I guess that's because it's more efficient at absorbing juice from inside the walls, and deck of the atomizer.
I really recommend using RxW 3mm BEFORE trying 2mm. I'll be ordering about 3 ft of the 3mm for sure. It's working a lot better than 2mm ever thought about.
