Glad you like it. I'm vaping a NI200 coil in the GS Tank that came with my TC40W and it's vaping great but I am running it at 450 to get the warm vape I like. Is that too high? I saw Busardo's vaping in the 450-480 range but I have no idea what kind of coil he had in it.Well my NiFe48 coil is still working really good. The last one I wrapped on my coilmaster so when I dry burned it it didn't get the oxidation between the coils. I'm up to 390F will keep you informed. If this one works like everyone says all I have to do is dry burn it brush off the gunk and put a new wick in just like Kanthal. The iron part of it causes it to take a little more power to heat it up but really so far not bad at all.
