Agree with whiteowl84, the two wires you mentioned are too close in size. The outer wrap of a clapton should be more to trap juice and expose the juice to small peaks and valleys for better vapor, the core wire(s) being the ones that really affect resistance and heat up. If you had finer wire like 32-34g what you could potentially do is a half staggered clapton (I think is the name).
Where you'd take the smaller of the two, the 28g, and clapton it with the finer 32-34g wire. You'd end up with a claptoned wire roughly the same size in thickness as the 24g. Then lay the 24g next to the 28g after it's claptoned similar to running two 24g wires side by side, then wrapping those together with a staple approach. Some complex coils are hard to do out of pure stainless because it's low resistance to begin with.
Too many ss316 cores and resistance drops pretty fast, especially on dual coil builds. Then you end up trying to add another wrap or two to get resistance back up and potentially end up with enough wraps that ramp up is slowed because it's trying to heat up in the center and takes awhile for the coils to heat all the way to either end. That's been my (somewhat limited) experience anyway. Trying to dodge low resistance issues on stainless steel with complex builds means going with finer higher gauge wire than you would with say kanthal and it gets pretty damn tedious.
Nothing wrong with experimenting and learning but if you're getting a really good experience on a simple build, don't discount it. In terms of functionality, a simple twisted build that tastes great to you is still a great build. Complexity doesn't always equate to better or more enjoyment. Most of the time I run twisted single coil builds using 26g or 28g ss316L.
