Hi Liam
I have the TI1, not sure if the TI2 uses the same kb but I expect so. I think the aftertouch is very well calibrated and robust. I find it very expressive, mostly, for adding some end-of-note modulation to mono leads, and now it feels like a completely 'natural' expressive element to the instrument. I've been using the Virus constantly for over two years now, and there's no problem yet with any of the keys. Since I play standing up it's possible that I tend to apply even more pressure than if I were sitting, too, and it ain't broken yet!
I've only played a Polar once, briefly, and wasn't really focusing on the aftertouch, so I can't compare the keyboards. I'm sure plenty of the Infekted here will be able to compare, though. And of course you might be checking the feel of the different models out at your local store.
