Wilky, you have the makings of a sensible person. But really, the only scary bit is the medical (as I get a bit older), the rest is as stress free as you'd like to make it. The bit that worries me about you though is your choice of aircraft. A PA28? It better than a C150/2 but really I'm sure you could do better. Maybe a Super Cub, a Pitts S2 or a Tiger? Get something with a soul!
