TC was adopted originally for rebuildable decks and specific types of wire. With a little practice, you can change things out pretty quickly. It's definitely not as quick as a drop in coil, but there's a trade off. The real benefit of RBAs is the cheap cost and longevity it provides. I have several spools of various wire and cotton that I can coil myself instead of worrying about a certain coil still being available in stock, or if/when it'll become obsolete. Luckily, Freemax is one of those brands that has multiple uses for the same coils, much like Innokin - and they're reliable. However, you can't bank on them being around forever. Coil and cotton, you can. Your mod choice is pretty good. VooPoo makes a pretty quality mod. Fast firing and consistent. GeekVape, also having the IPX (dust/water/drop resistent) is also a great choice. These are fairly middle of the ground mods in terms of cost, and they're quality. Lost Vape, Vaporesso, and Vandy Vape (I'm sure there are more I'm not thinking of atm) also make a pretty decent mod. If TC is something you really want to dabble with, you're going to want YiHi, DNA, and Dicodes chipped mods. Supposedly they are the best at performing TC functions, but I'm not fully knowledgeable about that realm, so you'd be better to ask others. Be aware of the batteries your mod uses if you choose one with external batteries. Battery size compatibility and the upper limits of your wattage are important when you choose which batteries you're going to put in it and what you're going to vape at. That's a whole different world of information that you should catch up on if you haven't already. Ohm's law and all.
