I haven't used the Engine or Nano but i have it right up there equal in flavour with the Ammit @kev mac may be more help he has the nano and has just got the Crius 11. I personally have used Nichrome, SS and Claptons and i rate it at least equal to any single coil RTA i have used.How does the Crius compare to the Nano. Seems to me there is not alot of interest in this tank. If I look at the deck design everything tells me it must be better. Is there anybody that have this tank and played around with it with different wire and builds??
