Pick your favorite brand - they all have a good tire.
I like to see what's on different bikes. Like the Ducati Monster has angels, the previous 'strada had syncs. Both get very favorable reviews on the V. I happen to like Pirelli tires.
Conti and BS are also known for good tires, road attack sport and BT021's always come up from those brands. A lot of guys go back to 'dunflop' and put the roadsmarts on and like them. I see the road attacks on some of the bimmers. Also interesting to see what the sumo guys run. There are 'sportbike' tires and then there are 'sport touring' tires. The former are softer with less grooving, the latter for better wear and rain capable. Some with dual compound for super-slabbing makes sense if you do that. Generally the sport tire is more rounded in profile and a more aggressive tire will be more pointed for a quick turn in and larger contact patch at high lean angles.
Unless you're a hardcore rider a sport tire will work fine. The V really isn't too hardcore for tires, so most all of them work well where you can get them in the right size.
Are you going to mail-order or buy from a dealer? If the former are you mounting yourself or having it done? If the latter, see what they have that you like for an installed price.
Tires are like oil and beer - everyone has their favorites.
