To mods: If I'm out of line, I apologize in advance.
To coastergenius: I've have just about enough of your somewhat smart-alecky comments, not so much because they are smart-alecky (I'm a cynic and all that too), but because most of the times you are wrong. Above, you tell Lynch that the proper term for upside-down is inversion. Look ou the word inversion, it makes NO reference to upside down (but does say inside out). Invert (verb) refers to upside down. Also look up loop and you will see that calling a 'dive loop' or a 'corkscrew' a "loop" is perfectly valid description. Your assumption that any inverting element is an 'inversion' refers to the connotation of the word 'inversion' NOT the denotation. A true genius would know when she/he was out of her/his league.

--- If it looks like a loop, and feels like a loop, than it's a loop.
