Kirby - I saw that but was in a hurry when I posted. It didn't effect the point I was making so I just left it rather than try to explain/clarify the explanation of the joint. Being familiar with the 97 I can picture the joint and, after making some unsupported assumptions of what was referenced, see how the explanation fits. In retrospect i can also see how someone not familiar with the design could misconstrue the explanation. I should have taken the time to clean the description up or clarify the terms used.
All things being equal, fat people use more soap. (I know I am one.
) High speed, low drag does not even come close to describing ME.
