Damn, I use 1.2mm inserts on all of my RTA's, hopefully it doesn't feel any looser than 1.4mm. I always found the FeV accentuated sweetness, hopefully the sputnik doesn't overdo it for me. I'm actually just waiting on an order of Flavorah tobaccos, and a bunch of mint concentrates to be delivered. Looking forward to testing them on the sputnik. Thanks for the write up!
