That's a pretty useful site now if only it were in the US... I bookmarked it though.
And I suppose you Europeans should have nice things too, LOL.
I find the N2 coils to be the trickiest, but honestly, I'm entirely uncertain if I actually NEED them to be TC that much.
For the masochistic among us, I guess there's always rebuilding the coil with a TC wire, the added bonus being you could target whatever resistance you want. I am completely clear on my lack of talent with coils, I have a feeling rebuilding any MTL stock coil besides the Joytech CLR coil (which ALREADY has Tc wires I think) is a task that I would find at best, horrific and at worst, impossible.
