Hey Ramsay, I got this knockoff version of the GV tool:
Original Wotofo Multi-functional Screwdriver It works great and like $2 (but 2.5 weeks to deliver). Thanks again.
I'm still having trouble getting these HBCs to work right, wick-wise. Lots of dry hitting and burning. GV Griffin, Kanger Subtank RBA... no problems, ever. For the HBC I have like a 25% success rate. When I get it right, the GV Eagle is the best I've ever had. I'm convinced my coils are fine, because sometimes it'll work poorly, then I'll rewick and it's great. I've watched a few Youtube vids and this is my current approach.
Relatively narrow wick, so it easily slides through the coil and barely scratches the inside.
Cut cotton ends at a 45 degree angle away from the base, starting at about 1-2mm outside the circle of the base.
Place the cotton ends right atop the juice holes with tweezers.
Is that basically what you do? Any tips? Btw, leaking is not a problem with my technique above. And I'm using Clapton wire from a 3mm jig. I can post pics if that'd help show what I'm doing.
