I haven't tried the T3s, but I might suggest the T2s to try as well.
I'd agree with trying a twist too and yes, they have a dial on the bottom to change the voltage - don't worry though it's not that complicated.It does add a cm or so to the length of the battery though.
I will add a Twist to the collection! Am I correct that changing the voltage is something that one would do to enhance the qualities of certain flavors? Extra centimeter...no problem. I'm getting used to the gadget now, it feels normal in my hand. I still reach in my pocket to check for a lighter though....
