After two days of exclusive using, I found Tilemahos v2 excellent! It seems it is more forgiving than KFL + regarding wicking; I had zero dry hits from Tily, although in two days I changed the coils and the wicks many, many times (just for experimenting

). I tried japanese cotton, bio cotton from ESG and rayon. All work, but I stay with japanese. I use only Titanium wire from ESG from now on, because it is cleaner (not so much gunk after heavy use). I had some problems with the juice control, because my drip tips slip when I want to turn the mouthpiece. Waiting for a GG drip tip, I found two workarounds on this problem:
1. Watching AdamAnd's video about Tily v2 (Vaping Canuck), I saw that he had the same problem and he unscrewed the top cap a bit. Well, brilliant idea! When you unscrew a tad the top cap, the big fat o ring that seals the space between top cap and mouthpiece loosens a bit, and then you can turn the drip tip and it doesn't slip anymore, making the juice control functional. Of course, at the end the top cap must be tightened.
2. Vasilis from ESG tought me another trick: removing the drip tip, placing a small bit of resistance wire into the mouthpiece, touching it's inner wall, and putting back the drip tip. The friction is much better now and the mouthpiece can be screwed.
P.S.: perhaps thicker o-rings for AC would be better; I find the AC ring turning too easy.
