I am interested in rooting for Ice Cream Sandwich

you left out one very big step... I always backup the dcmia ringtones notifications to my PC then reformat the internal storage card as not to have any issues. Then I copy over the rom.zip file to the internal storage and then turn off the phone and boot into cwm and then do a nand backup and then wipe system cache data boot and delvik and then flash the rom

Personally I never wipe/format the sdcard storage. Never have had a problem and as you can probably guess I flash a lot of stuff especially when I'm developing themes.

Not that this is a bad practice your suggesting but I believe its an optional step or should be considered if your having previous issues then yes its a great suggestion

Im with ya paul, I never format /sdcard either. And like you, I've flashed more times than one can count. Lol.
