Glad you were able to stay right-side-up!

I pretty much do
not use my rear brake on wet roads. 70% of stopping power comes from your front tire in dry conditions, I figure that front tire stopping power jumps up to at least 90% on wet roads. Basic physics comes into play when you think about it. All that weight shifting forward as you slow down renders the rear tire almost useless as it tries to lift off the pavement. Just tapping the rear brake will stop tire rotation. The results are obvious.
I always felt comfortable on the Elite III's in wet weather...racked up way too many miles on slick roads with those tires. They always stopped and cornered fine. To date, I have not gone out in wet weather with the new Elite IV.
The Michelin Commander II's and Commander III's use a "silica reinforced rubber" that really sticks on wet pavement. Reviews indicate that Michelin's wet weather performance claims are sound. Unfortunately, Michelin does not make that tire for the our Valkyries!
Dang!
