If I recall, you'll be near HOT'Lanta. The high wing is the plane for you. Easy to fly, forgiving, good glide characteristics, great view, and the cold fuel in the wings (along with the shade) helps keep you cool.
I learned to fly in a cherokee 140 cruiser, with stubby little wings and the landing properties of a brick. I haven't flown the low wing you mentioned, but consider this: when you want to rent an airplane, the 172 is likely to be the plane that's available. Time in type is a big plus, so start now.
Back to trumpet practice. Good luck.
