The V700's always were good to me, but really there needs to be standing water to make them better than the A6. I've driven my A6's in the rain against a guy on Kumho V710's at a Divisional, and the time difference was the same on Saturday (Dry), and Sunday (wet). On the wet day, those with Hoosier Wet's owned all, with the exception to the STU subaru's that were on Bridgestone RE01R's.
Light rain sucks, because the treaded "Street Tires" like Bridgestones, probably aren't any faster than the R Comps- it would certainly be interesting for someone to test back to back. When you get standing water is where it makes a difference, and at that point you want to be on the Hoosier wets. That said, the best intermediate tire options are probably the V700, or the Bridgestone.
