I've punched small holes using the saddle valve on Boge 3.0 cartos and juices have wicked great in every one of them (VG heavy and PG heavy). But I'm having problems with these
Mega XL HV 2.0 ohm dual coil cartomizer with the VG heavy juice. The PG heavy juice seems to wick, but it seems a lot slower than on the Boge's (they will still crackle). But with the VG juice, it seems it stops crackling after the juice that I pre-filled in the carto is used up. I've tried one hole (the way I've been doing it on the Boge's), two holes (same as on Boge's), and one larger hole, and two larger holes.
I'm wondering if the filler material is different and has a harder time soaking up from the tank. Anyone by chance using any 2.0 dual coils with more success than me?
