Is there a good photo reference somewhere for identifying the more commonly available types? Or,more specifically, tips for narrowing down the possibilities ? I see there is a 50 page database here with many good photos, but, say how would one know the difference between 'Pascal' and 'Luca' which look very similar in the photos (to me, anyhow!). You don't have to be gentle if the answer is "it's hard to tell", I can deal with it....
