Familiarity: I've put it through the wringer
I've been paddling a Zephyr155 for two years now. Bought primarily as a day tripping river boat. Its been a blast in the canyon reservoirs of the Rocky mtn region and on the North Platte river. Its excellent maneuvrability makes it a fun kayak to play in but also lends itself well to rough and stormy waters. It tracks nicely if you have a decent forward stroke and the boat responds to skeg deployment very well, often just a bit of blade deployment will keep you on the straight and narrow. The Zephyr may feel tippy at first due to its rounded hull but even a novice will quickly grow comfortable in the boat. Advanced paddlers can make this kayak dance.
I've recently returned from a backcountry trip in the Yellowstone and Teton area and used this boat because the weather was simply too bad to take a canoe. I was able to pack for 5 days with the judicious use of compression sacks and good modern backpacking gear. Total kit weighed about 55# and I weigh 170#. The Zephyr had no troubles at all in the rough waters. I also own a Valley Nordkapp and paddled Tempests for many years thus my comparisons are against some of the finest touring boats available.
The Zephyr gave me the advantage of one boat to do it all this time in the Tetons. It handled Leigh and Jackson lakes with aplomb and then followed up with a nice Snake river run. Hard to beat that kind of versatility, especially when the boat is just so much fun to paddle.
When I return to the Tetons and Yellowstone for next year's adventure it will certainly be in the WS Zephyr 155 again - it has earned its place as my primary boat.
