I have a paddling background that includes recreational racing of sea kayaks in the 19' range, surfing and rock gardening in 16' range, plus WW in an 8' hard shell, a 6' hard shell, and my inflatable Alpacka. My sea kayaks all have rounded hulls with widths of 22" or less. They can all be paddled with a high angle body rotation racing style without any concern for tracking. My 8' WW boat, my 6' WW boat and my shorter Alpacka Yukon Yak all have flat bottoms and hull widths greater than 25". These WW boats all zigzag, even when I paddle parallel to the boat's side. I don't anticipate that the improved tracking would noticeably increase a 2011 Alpacka's hull speed.
I have many different WW and sea kayaking paddles. There are models that handle WW better and models that handle touring better. That said, the Sawyer is the best option for a combination paddle to do WW, flat water, plus act as variable length backpacking staff, and variable length shelter pole. The paddle shaft and variable length flick-locking mechanism are extremely robust. The rubber bumper will wear through after one to two weeks of trail use. I buy the inexpensive packs of four 1 " white bumpers sold at Home Depot (#89121) and replace it when the wear pattern removes the two circular ridges.
