I'm in the 2k16 buttfill category - just prefer it more
....... I kept the original drip tip that was sold with the sxk 2k18 topfill version in my kitchen drawer. When I filled, I whipped out my current drip tip - stuck in the fat original one, did the JFC thingy, filled, undid the JFC thingy, took off the original drip tip, stuck mine back on and vaped
I'm not sure what drip tip you are using, but I found it easiest to use the JFC with the original one. Which is kinda why I prefer the 2k16 over the 2k18
Welp, color me forgetful. I don't even KNOW what tip came with the upper body DogFill! I found some old (old skool) tip that works to open and klose the JFC, and that's my go-to now. Perhaps I should search the Interwebbies to see which tip was the OG?
Unless you wouldn't mind skooling me, Madame Ange.
