Everything should work on the VT, it's just a regular 510 connection. I wouldn't screw on the tanks too tight if they have a very long 510 connection though. I think I messed up the 510 pin on my VT that way. It's not a huge problem but I had some problems connecting it to an rta with a shorter 510 connection afterwards. It was an easy fix though, not a huge deal.
Mine lasts me 3 to 4 days on a charge but I vape in Temp Ti mode with the max wattage set to 32,5W, and I guess I don't chain vape (often).
The only thing it won't do is SS coils in TC mode, at least not without being a hassle from what I gather.
But I love mine. It's real easy to use one handed with the rocker switch and straight forward menu, feels solid and well made, looks amazing (imo), and is still pretty small considering the battery capacity. It does have some heft to it though.
Thanks for the detailed info! So if I use SS coils it would need to be in the normal mode and not temp control?
