I prefer saddles also. The one shown

via the link, though, might have two problems. One is that the location tracks for knee cups and ankle supports do not conform to most anatomy. When the knees are spread, the lower legs want to slant toward the center of the canoe, not straight back toward the stern.
The other is that there is no support thwart for the saddle. Saddles just attached to the bottom of the boat don't usually have enough stability, and contribute nothing to the rigidity of the hull. A thwart across the high part of that saddle, behind the paddler's butt, will hold the saddle firmly in place and provide protection against the hull being folded in a mishap.
