Just built it that way to keep the coils high up and the same height.
What is the advantage of having one coil high and one coil lower?
Would it be better flavor? Would it create more vapor?
Using the same post holes was a simple build. Fed them in, held them tight to the posts and torqued then tweaked and fiddled.
I could do that build no problem but way more of a hassle having to bend up and bend down the horizontal coil leads to hit both posts woth out distorting the coil...No? I could see it on a vertical coil build but still the same problem and if you want your coils mounted higher, the bottom post hole leads would keep the coil too low without having to have a 7mm lead...plus, the post holes are like 5mm post holes...I mean you could drive a Mac Truck through them. You could do dual Claptons through the same two post holes[emoji13]
It's actually EASIER to keep the coils at the same height with the bottom/top method, it has more mechanical stability, better connection, AND it has shorter legs, EVEN legs. On your build above, your bottom leg is about a third of a wrap longer than your top. That's kind of a big deal in TC builds (Kanthal, not so much). Finally, you can build one side at a time, get it tight, and then do the other, since you're not sharing post holes, which makes for tighter, cleaner builds, with the shortest legs possible.
Doing it like the picture below, the legs just naturally go into the upper or lower holes, straight shot. If you want the coils higher, no problem, it'll move closer to the posts when you lift it but it won't make for longer legs. Same in reverse if you want them lower.
