Well... my understanding is that things can break rather badly if you 
use reiserfs for the host, and then use reiserfs for one of the guests...

totally correct that it 'doesn't matter'...

Possibly a valid argument overall... would like to see what Stan has to 
say about it though before I make a final decision...

Thanks to all for the replies so far.
