IMHO there is no better combination of DDing than a BT-45/B-T46 mounted front and Radial CT rear. My experience was on the infamous pothole roads of NE Pa. which provided riding on numerous road surfaces with literally tons of anti-skid material come spring. I recall posting my experience with the BT-45 early on, as turning my F6B into a "Corner Carver" and after 50+K miles my view of the BT has not changed. If you want sure footed traction, Double Dark Side is the route to go.
