I know the feeling.... I never even tried temp control on any of the demos, I just never had the time; honestly I still don't but sometimes you have to make the time, that's what I did today. I have a pair of Dicodes 6's that got me started on NiFe, would you believe me if I told you the dna75 does nife30 much better than even the Dicodes? I don't blame you... I wouldn't either but it does. Much smoother which yields much cleaner taste. 2 days on the same wick with Dicodes in a hurricane and my wick looks like charcoal, on the dna75 (which should use the same algorithm as the 200) 2 days on the same which and it's off white. Same Carrot Cake juice that Russ has made so famous.
