Andrew, the 150/150 does everything that we require. We have no real need to go higher performance. In fact, it is nearly the perfect airplane. With the exception that it is "certified" and has a gross weight exceeding 1320 pounds. We just want to climb out from underneath the FAA's thumb. With an airplane that also may be a bit more thrifty on the fuel. In other words, we want our cake and eat it too!
