I look forward to hearing more. I also have an '07 RSV. Mine came with the Dunlop D404's as the stock tire. I've got just a little over 8,000 miles on it. (I've only had it since April. When I got it, it had 1,400 miles on it.) I'm about to ride from Baton Rouge to North Carolina to ride the Dragon and the Cherohala Skyway with some friends. This'll be my second trip there this year and I suspect that it'll be time for nwe tires when I get back. So, I'm busy trying to decide between the E3's or the Venoms. I like what I read about both of them and I'm sure I won't go wrong with either. I've also been quite pleased with the D404's on this bike as well as a previous bike.
I'm running close to sensory overload already in trying to make a decision but... I keep telling myself it's not that big of a deal. Both are great tires.
