Yes, and I remember when the kinks were introduced.  Through-hole 
4-layer circuit board for a vehicular and aircraft application, I gave 
one of our prototypes that had been auto-stuffed to our Mech E. and told 
him to put it into his shake-and-bake, and show me the vibration spectra 
when the parts fell off.  Every single one of the kinked caps flew off 
at well below our contract vibration specs.

I don't subject my K2 to anything like that, but I have dropped my pack 
a couple of times [and knew I would], and I straightened all the leads 
and put the caps right down on the board when I built it.  It's a little 
more work, I figured it was worth it.

73,
