I dont know if the DA 50 will have enough power but you may look into a ZDZ 80 or maybe even a 60 might work. I have heard nothing but good things about the 80 although i havent really heard alot about the 60. Im sure that it is just as good as the 80. And yes they vibrate, but dont you think that DA50 will too. They are both big singles and vibration comes with that. But i have heard that they dont vibrate near as bad as what you would think. As far as planes go, If you just have to have a DA 50 i would look at the new WILD HARE EDGE. It looks like a real nice plane. Good Luck with your decision
