For a good, all-purpose solo, I like my Wenonah Wilderness quite a bit.  Picked it up as a demo boat from Midwest Mountaineering a few years ago for a third the price of a Prism or Q16.  On a 16-day trip down the Bloodvein it handled most class I and II rapids, blasted through big waves, tracked well on the calm flatwater and had plenty of capacity for all my gear (100 lbs of gear, 180 lbs of me).  I have the 49 lbs royalex layup which, to me, is a nice compromise between weight on the portage, and utility on the water.  My paddling mate had a Bell Wildfire solo (also in royalex) and spent most of the trip out in front of me.  His boat seemed faster and more maneuverable in rapids, but my Wenonah seemed to have more carrying capacity and tracked straighter out on the big lakes.  I don't mind the heavier royalex canoe over a kevlar because the smaller solo royalex boats are light enough for me, and then I don't have to stress as much about hidden rocks damaging my hull.
