Thanks Eric and Brian for this useful information.  I appreciate the input by both the scientist and salesman!
I did mention Velscope which got very little reaction but I have learnt a lot and it is here for others who may want to search on the terms listed. 
I guess the main thing is that the 5 minute visual (oral look and feel of nodes) with the surgeon produced a �Looks Good� comment  

Next appointment in 6 months time but have one at the CCC on 21st September which I know is just doubling up but if it puts my mind at ease.....
