C/D liked the Hankooks and Kumhos better than the Falkens.

And Sumitomo makes some good tires. The IIIs kick some butt in the dry beating the RE050As, etc..

I have autocrossed and track driven the 615s numerous times in pouring rain. At or near full depth they move way more water than you would expect but granted, not as much as a V pattern street tire. Mike and I still remember that autocross in Lovelock as one of the most fun ever!
Again, they are all good tires, don't let Kevin convince you otherwise.
I think the flexibility of the V12 to be flipped, C/D review, price and treadwear would have me leaning toward them.
