I have a vantage which is the same machine minus the deck. All i can say is get the biggest motor you can for the model you want. The hill stability is ok at best. Be careful going up because the front end likes to pick up, and the side to side mowing you just have to go slow otherwise you will slide. The one thing that I do love about the machine is how it will just float over soft ground or water. It really amazed me this spring due to us(ohio) having rain just about everyday and making lawns lakes!
oh and make sure you spend time getting the controls right they are a bit touchy. I hope this helps!
