I wrote a review of the Kenda Slant Six tires with a bunch of pictures on my team blog. If you'd like to read it the address is:
These tires ride great. I’ve been up steep rocky climbs without breaking traction in the rear, even when there is loose gravel scattered over the trail. I’ve ridden miles of paved and gravel roads and they felt smooth, fast, and quiet. The loud annoying ‘buzz’ you hear from other tires is not as prevalent. The small ramped lugs on the tread centerline do their job as advertised, the gently ramped front provided a smooth ride and the abrupt end on the tail of the ramp providing great braking.
