As my 30Ga Tempered Nickel wire won't get here till tomorrow (Maybe), I went ahead and did 12 wraps of .4mm Titanium1 and the coil reads out at .44ohms, flavor is great, and "Clouds"! What a bummer to squeeze all that cotton back into that little case, tried rolling it in, Nope, tried squeezing it in with my fingers, nope! Finally ended up poking it all around the bottom of the cotton while trying to ease it in, Yep, that worked! Wasn't really worried about pushing on the coil, as I had to do that to get the spacing after pulling it out a bit in the first place while it was still on the 2mm rod of the Coilmaster V3 that came the other day with the Ti .4mm wire! Had to find a spacer that passed the raised center of the top cap, but still supported the rest of the top cap so I could whack it back in with a tiny hammer! Tried putting it in the base and screwing the tank together to press it in place, but that just left that darned top cap stuck in the chimney! Luckily the 2mm rod popped it out of there! I'll try a nickel build tomorrow after the mailman gets here. I'd much rather NOT run my iStick TC 40W in Ti mode! Using the GS_Tank with the new Ti coil on my Evic-VT right now! 440F with Prince Pucker max VG juice from Vape Moar! Crazy prices, 10 15ml sample bottles, thats one of every one of their ejuices for 20 bucks and free shipping! Their 120ml bottles are also $20 with free shipping! Heck of a deal, as there was only one of the 10 that I didn't care for at all! 110ml of good stuff for less than 30ml around here!
