I had 27" Vampire's the Claw's rule. I love them. I wouldn't trade them for 2 sets of Vampier's.
IIRC they only make the MAGNUM claws anymore and those are the 27sThe bi/tris that are not 27" are alot different than the 27"s. I believe one is called "Magnum" and the other is not. (not sure which is which though)
They do OK in the snow, its just like sand tho, take your time giving gas or youll end up in China before you get 5ft. They are GREAT for snowball fights though, mine thow up baseball size snowballs, if you drive fast enough you will drive into them. Its also fun climing hills with them, you can actually see why they are called CLAWS. They will "walk" there way up the hill, and with the 3wd of our hondas its even better as one tire slips and the other grips back and forth all the way up the hill, just like its CLAWing its way up.I got a set and love them, and with a clutch kit they turn just fine. With a pipe and jet would turn them even better. They are a great tire, can't wait until snow to try them out in that
