Thanks daveopam..
I am a frequent flyer of many moons I never realy took an interest in new terminology being used I have heard the term and seen it often over the last few years or so usualy in mags etc. always seems to be used on a cover somwhere with a pic of a 30% dragging its tail in the grass.I do think I do have a better understanding.
I guess I need to stop training so much and actualy read a mag once in a while.

WCB great interpratation

I love this stuff....................
