Sorry for the not replying sooner.
Looks like it will be the falcons then - They've got to be better than the triangles on the front currently!
Incidentally I didnt have any issues during the snow, I had the rear breakaway occasionally on the slippy roads but considering its auto etc I think it faired pretty damn well. I only got stuck when I parked in some deep snow which most cars would have got stuck in!
However I had planed to get winter tyres this year but didnt get round to it in the summer, then changed cars etc so if I still have the LS next year I'll properly get a set, I do think they would be worth the investment if you really need to get to places then you shouldn't have any problems..
