Hi Loren, Thanks for a very informative reply...you've covered all my bases and given me a very good insight about what you did at a behavioural level. Next I want to know how to get hold of John's Advanced Modelling audiotapes...so if you, or anyone else reading this can give me a lead...great! You wrote:"I'm not sure if the "For example" bit is asking about a lifeline or how I personally make the shift to 2nd position". It's both elements! You also wrote:"Now that I've written this down I'm feeling a little lost in the process." I trust that the information you've gained will allow, once the dust settles again, an even more streamlined version for your next modelling project. Best wishes, Lewis.
