I love the new products that keep coming out for us vapers... Titanium Fiber Cotton is brilliant to work with and excels in RTA's and is my number one choice. I still love Royal Wick also for RTA's. Cotton Bacon V2 for my drippers and squonkers. I'm going to play more with Cotton Bacon Prime when I start testing REPLAY on the DNA250C in drippers! And I must say I love the little tins the TFC come in... a lot easier to close than those wannabe zip lock bags.
