RE: P51 PTS or Arrow trainer
As for your wanting to fly warbirds, that is a great aspiration. They are some of the neatest planes around. They will not make even a good second plane, however, and you will need a good transition plane between your trainer (whether you go with a high wing or the PTS) and a warbird. Think of it this way. When you started school in the first grade, you didn't begin the first day of math with trigonometry or statistics, even though that is what your schooling would eventually lead to, did you? You probably started just like every one else, adding two apples to three apples to have five apples. Then you went on to a transition plane that was too difficult for you to fly on the first day. You started long division and multiplication. Then you found a decent warbird, or an extra, maybe even a pylon racer and did algebra. Then you got adventurous and did trig. Maybe calculus. You scratch built a giant P-38, or a turbine powered F-22. Whatever you fancy. And a high wing trainer will not 'fly itself' it just helps YOU learn to fly the basics.
