I purchased the Jazz "Tripper", sight unseen, after seeing it advertised in a kayak magazine. I call the distributor to learn more about it's construction. The blade is a carbon fiber fabric, toughened with epoxy resin, using a proprietary resin transfer molding process which makes the blade more resistant to de-lamination and edge splitting. Sounded good to me.
The Jazz has a "Quicklox" adjustable, take-apart, connection for both feather angle and length. I found this connection to be very positive and reliable. The blade is a very generous blade, about 19-1/4" x 7-1/8" by my measurement. It has a subtle dihederal and a slight spooning which contributes to a smooth and flutter free catch.
From a personal point of view, the fit and finish of the Jazz paddle is impeccable. The balance and swing weight is near perfect. My paddle weighs 30 ounces, and the comfortable shaft is easy on the hands, after hours of paddling.
This paddle has become my favorite over all the other paddles I have used. After two seasons of constant use, I rate it a well earned 10 out of 10. This is one paddle you should check out. You won't be sorry.
