ditto on that. I need to order some prebuilt SS coils next FT order as I prefer TC mode but am too lazy usually to twist up some ss wire and coil it so lately I have been digging into the 2 x 48 packs I got on my last FT order.I am using rayon almost exclusively now and love it.
I have tons of wire (2000 ft likely) but am finding the I grab pre-wound coils more and more. The $7 fasttech packs of 48 coils (8 different kids) make it hard justifying paying $15 for a small spool of Clapton wire or making the Claptons (or other fancy wires) myself. Forget about the time spent making coils.
