Yeah, that's it, problem is I was using 24g Kanthal, it was too big to go into those holes (was thinking about drilling them a bit larger). I have some new wire coming but was looking to play around with things while it's on it's way. I have some 26g which I twisted and put in the dual RBA and it's working splendidly but I wanted to make a vertical in the single. From what I was looking at, while I can do that with the 26g twisted, it's only 2-3 wraps to get the resistance I wanted, where I was hoping for 4-5+.
