EASIER FOR THE TEST!
An aeroplane is an aeroplane. Its what you are familiar with. You'll find the schools will have Partenavia's, Travelairs or Seminole's as options.
Twin's are not all that easy to hire - especially with low twin time. Your options are likely to be either the school you use or Blue Demon. Thats why I suggest thinking about what aircraft you want to hire then using the MECIR training to build hours on type.
