I too am a fan of FexEx'ing my clubs.
But no one has asked the obvious: why not rent clubs?
It sounds like just a friendly game, and most clubs these days have very nice rentals.
Even though I'm 6'8 and have custom clubs, when I'm just playing 1 round on a trip, I always rent. Not worth the hassle to bring them, and it's cheaper than shipping them.
And regarding the other topic, as a frequent flyer my main concern is seeing the intrusive pat down of our elderly. When I see an 85-year-old woman (who probably has multiple steel hips and/or knees) being made to stand up from her wheel chair and waddle through security to get further groped it incenses me.
