Instead of buying something new, maybe adjusting/changing your rear shock may give you what you are looking for? The Hei-Hei is a decent bike. As for the turning, if you are having trouble turning a 29er, I assume it is at slower speeds. If so, then try to keep pressure on the pedals to help aid the forward momentum. You may find it easier to turn and maneuver through/over stuff while turning the pedals vs. trying to coast through the corner. It is also easier to maneuver any corner if you are out of the saddle. You also may be turning-in a little early, but I'm merely speculating.
