Hi Sushee - Forgot to mention that I visited the acrhived thread you mentioned which was very useful, i then also spent some time on various web sites some quoted.

It's clear there are a varying number of opinions on what's best and no doubt there will continue to be useful arguments for both sides. I decided to stick with blasts for this cycle and am comfortable (But praying all the same) that we will have some great little embies left for freezing ........
