The middle Blackhawk Combi is a great canoe for most of the Midwest. It lacks the capacity needed in a tripping tandem, but is a great all around canoe that is at home here in Michigan. It is great on lakes of all sizes or on rivers so long as they only contain class I or II whitewater. The boat is small, but fast and responsive.
The 15'8" is not the best solo that Blackhawk made, but solo's better than any other tandem I have tried. As a solo tripper it would really shine. These are great boats that have not been made in some time now. If one pops up for sale you should only test paddle it if you can afford to buy it.
