Why is low level showboating? I have around 1000 hrs below 100' occupationally flying long cross countries following pipelines. I learned to be safe and comfortable down low. Coming back from OSH last summer on the Atlanta to Ft Lauderdale leg I made it through on the deck off the beach in perfectly safe weather conditions when airliners were waiting out the system. As for wires, as soon as you see horizon under them, forget about them, maintain your focus on the deck clearance and you'll fly under them. If you look at them, you'll hit them. Trying to climb over wires at the last moment will typically catch you in them, best to go under. A 152 for example will fit between the fence and the cable TV cable in most neighborhoods, concentrate on end point of the glide path that takes you across the fence, then pull out. This is the same technique Ag pilots are taught to fly under those wires all day.
It's only 'showboating' if you do it for that reason. If you have operational cause it's a viable tactic. If you do it for joy, well, that's valid in my book. BTW, I own a HP twin for a reason.
