Hey Guys, I have a TFV4 and and an XCube II setup and it was working great with the quad coils at around 70 watts great clouds and rarley ever a dry or burnt hit, but stupidly I decided to take a chance and try the temp control coils so I went to the shop and asked for a pack and put one in and primed it and well it works okay but it's kinda mediocre and the vapor production is crap compared to the quad could and they said the flavor would be great with these but it's total crap always getting random burnt hits out of nowhere and it's titanium coils but the only option seems to be nickel on my XCube so that's what I'm running it at and Mabey that's the problem? Also the hits feel rather softer and less vapor is getting in my lungs and it kinda just sucks..... Any advice for getting the temp control coils to work better? Because I have 4 more of them and I would rather not throw $30 down the drain if I can avoid it and have to spend another 30 to go back to the quad coils! Any advice you have in this department is much appreciated thanks guys!
