I like the UST 2.1 nevegals! They have plenty knob for cornering, enough volume for suspension and yet have wide spaces to shed mud ( no need for changing every 2 days) plus ramped knobs for good rolling resistance, rubber durometer is somewhat grippy, and tire wears well . If you run the rear according to manufacture's direction you will have increased braking power but may lose some traction control. If traction is your thing, there are better grippers out there, but they may not shed or wear as well. Always a give and take.
