You are never going to get incredible dry grip with good light snow traction. Maybe my impression of incredible is different than yours, but if you aren't running DOT slicks or stickier, you aren't getting incredible traction in my books.
Spoken for truth.
Good rule of thumb for sure.
I miss my A032's for their combination of DOT slick excellent dry traction, awesome wet weather performance (at full or nearly full tread depth), and reasonable wear characteristics... if anyone knows of something that meets or exceeds on all 3 points, I'm all ears.
