Colyn, with the gasser in the front of the 150 you may have too much weight in the front, which would make it hard to land, more speed is required to keep the elevator effective. My 150 is nose heavy with an OS 1.60, your's would be even more nose heavy, I am not a 3d flyer and the harrier landing is easy with the 1.60 in the nose. Check your CofG again.
