Thank you Tom, as I said at the start I was looking to be educated and to better understand why people are making the selection they do - what makes a person select the 18" and another the 15"...
But as you say, I am asking the impossible - so I will consider myself educated (but still a bit confused - or is that ignorant

) and leave it at that...
