BMW-K,
You have some good choices but my two cents would be to cancel the VTR1000 off the list. Nice motor, but the suspension is way out of date and it gets really poor gas mileage even for a big twin. Since you already are a BMW owner, I would think that the R1200ST is too close to what you already own and that the K1200R maybe exactly what you really want. The ZX-6 is a little high strung, but not unpleasantly so and since the XB12R is my Lightning's kin, you certainly can't go wrong there!
Summer is coming so just pull the trigger on one or preferably more than one!
