Interesting video from Rip Trippers today, he has just done the Clapton and uses 0.4 mm guitar wire as the core and I must admit it looks much easier to do than straight onto kanthal. I was saying last night at the vape meet that as there were dna20 mods around it would have been good to try one as IMHO it does need the power output to drive it properly, Rip went straight in at 22w
