Thinking of trying out the Vision 120 SP actually...its 12'x23"
Other boats on my short list are the Alchemy 14S (14'x23") and Eddyline Samba (14'x22.5"). I've test paddled none thus far though. The Vision is attractive to me on paper because it has the arch hull and smooth chines that I favor, where as the others (I believe) have more v-hulls and harder chines.
I use a WS Tsunami 135 at work (13.5'x22.75"). Its a good fit, but way too straight a tracker. For my personal boat I'm favoring maneuverability over tracking.
I'm actually obsessed with how my old-school MI415 fits/handles (14'x23" pic not of mine): http://img13.imageshack.us/img13/85/imgp0553p.jpg
but want something more practical with bulkheads, perimeter lines, etc.
So with that in mind, other suggestions welcome in addition to any info on the Tahe Lifestyle Solo.
