Awesome build bro! Is the Trident your first RDA? That's crazy because it was mine as well, to me, it was pretty hard to build on man! Those little slots for the wire are tricky to hold just right while putting the little post cape on. I tip my hat to you sir for building a parallel in'er lol.
If your looking for a really capable dripper in the future for post holes, I recommend the Brass Monkee. It has dual positive posts, which makes basically any build a breeze. That was my second dripper, and that's when I really got into making really pretty coils (because it was so easy

.).
Isn't Gplat amazing? I have the 22ga "elite" and every build I've made with has been epic. I'm pretty sure 28ga gplat, and 24ga kanthal have about the same ohm rating, so nice pairing. If your having problems with caramelizing cotton, try and get it in as loose (and as less as possible) as possible while still touching the inner rim of the coils, if it's too tight it'll just burn easier, and taste like cotton.
Again awesome build brother, god knows parallels are nearly impossible to get perfect. If you were wondering what the brass monkee deck looks like here's a pic. They even have a nice clone out if you'd rather save some cash, this is the authentic below:
