I wonder how much better Spider Silk is compared to Sweet Spot Ti and how much is hype. $1 a foot the way I go through wire could get real expensive depending on how long a coil lasts. I can't find anywhere what the resistance is per foot of Spider Silk, Sweet Spot is 1.2 ohms per foot. Then I wonder if Sweet Spot is any better then Unkamen. Guess I'll wait and see what others think. Just use nickel for a while I still have about 150' of that.
I just calculated it out on Steam Engine... For a 2.5mm coil with 6 wraps it is .246 ohms using 2.456 inches of wire. If you use a 3mm coil you will get .028 with 6 wraps.
Now if you go for dual coils, you could build 2 with 8 wraps on 3mm giving you .187 ohms, or with a 2.5mm with 9 wraps would give you .18 ohms.
All are assuming their default leg length of 2.5mm each which is on the shorter side.
My Zephyrus and Mutation X v4 just shipped so they will be good dual coil RBA and RDA for my testing with dual coils which seem like the way to go on the SXM which can handle the lower resistances.
Even at $1 a foot for the SpiderSilk Ti wire it should cost me less than dollar using 3.686" of wire plus about 6" of waste wire. I can afford that considering all the junk juice I have bought over the years.
