I do jointing with cherry, red oak, and pine all the time. Getting the seam to be... uh seamless is easily done as long as the joining surface is straight and flat, which I easily do with a hand plane. Not sure if you`ve done it before but check to be sure the edge is perpendicular, glue it, and clamp overnight. Clean the face of the seam with your plane and you wont be able to feel it, seeing it will be dependant on the grane. As far as strength the glue is stronger than the wood so biscuits wouldn`t be needed so long as its paralelle with the grain.
