Recently got my 3rd kayak, a composite Vision 140 by CD - a few years old, but in dealer-demo condition. Stiff, light, and durable... very responsive, and tracks well without rudder.
Rudder and special seat add loads of comfort and control.
Very quiet thru the waves, and swells I see in "big river" boating.
I am 6'0", 170lbs, pretty fit and have easy entry/exit into the keyhole cockpit.
Excellent quality, and craftsmanship displayed in all aspects of this craft.
