sorry you haven't had any responses yet but I would guess that most TW vapers would not be familiar with the kit you have, so would be unable to help.
I started out with the kit you have and liked it in the early days, but quickly became tired of charging batteries all over the house, so I moved on to a bigger battery capacity with a Tornado and it's a far, far better experience for me. Especially the passthrough, which ensures you have a full charge when you need it; I just unplug it from my computer and take it with me when I leave the house.
I tried one of my clearos in the PCC which you have and I'm afraid it doesn't fit, even in the spare battery slot; but the only reason I needed a PCC with the previous kit was to ensure I had a charged battery...the Tornado does me for a whole day with a fresh charge so I no longer need the PCC.
BTW there's a good carrying case for Tornados with plenty of room for spares; it also has a charging case if you need it; or the smaller, slimmer model, the Titan has a PCC too.
I'd recommend you take a look around the forum and the website at TW, ask a few more questions about what you think is the right kit for you to make sure you're getting what suits your requirements. There's a friendly, helpful crowd here and IMHO the Customer Services are second to none. And way
better than the current supplier you have, and that's from personal experience too!
